The dog days of summer…

By the time midpoint of summer heat arrives, I am firmly in ‘summer hibernation’ mode.

While much of the country stays indoors during the cold of winter, we desert dwellers flip that and spend the hottest days of summer safely ensconced indoors in the comfort of A/C.

Of course, cabin fever can hit, making us venture outside of our homes. That’s where summer getaways come into play.

I’m fortunate that there are many spots in Arizona (where I live) that are just a few hours from my house where the summer temperatures are blessedly cooler.

When my husband and I were young, we couldn’t afford to stay overnight in out-of-town destinations. But, we could go for the day. We would pack up our two young daughters and go on day-long adventures to the cool mountains and pack a picnic lunch. Oh, what fun we had!

Nowadays my husband and I travel to cooler spots and spend a few days. One of our favorite places is the town of Bisbee in southeastern Arizona.

There is a lot of history in there and we love to explore while enjoying the cooler temps. The photo above is a part of Bisbee called Lowell, which is preserved in time from the 1950s.

Speaking about the heat, I’ve heard from a number of people in my membership club who are worried about the lack of flowers they see on their shrubs and groundcovers.

Perhaps you have similar worries…

I want to assure you that this is normal in summer – particularly when monsoon rains have been sporadic and not regular.

Intense heat and dryness tend to make flowering plants slow down and a heatwave can burn flowers of certain plants.

Rest assured that they will come back by summer’s end to provide beauty to your outdoor space.

flowering groundcovers and a cactus landscape

Let’s face it…summer can be brutal.

I tend to spend as little time outdoors as possible when temperatures soar above normal ranges. It’s times like this that I praise the inventor of air-conditioning.

While we can escape record-breaking temperatures, our plants can’t.

However, you can create a landscape filled that thrives in the heat by using native or desert-adapted plants. And you know what? Most are very pretty!

Last weekend, I saw a great illustration of this…

Our church recently opened up a new campus, filled with new plants, but many of them were struggling to survive the intense heat. Many were planted native to more tropical climates.

After church, my husband and I headed out to the hospital to visit a loved one. The hospital had just undergone a renovation and brand-new landscape areas surrounded the entrance.

I stopped to take a photo of one of the areas that were doing very well so I could share it with you. Full disclosure: if you hang out with me, be prepared for sudden stops to take pictures of plants.

There were two main reasons that the landscape by the hospital was doing better than the one by the church:

  • The plants by the hospital were better adapted to hot summers – desert marigold (Baileya multiradiata), gold lantana (Lantana ‘New Gold’), and Mexican fence post cactus (Pachycereus marginatus).
  • Additionally, these plants had been installed three months earlier than the ones at the church. Yes, plants can technically be added any time of year BUT there are times that should be avoided if at all possible – specifically May and June.

Sometimes you need to add new plants at the wrong time of year due to construction schedules, etc. In that case, I advise the use of shade cloth on a temporary basis for young plants through September IF you see that certain plants are struggling. This is in addition to watering them more often than existing plants in the landscape to help them establish their roots.

Use native or desert-adapted plants (those from other regions with similar weather conditions) to help your garden to be more resilient to hot, dry temperatures and they will need less help from you to beat the heat.

Stay cool friends!

Have you ever noticed circular areas missing from your leaves? If so, you aren’t alone. The other day I noticed several of my plants with neat semi-circular sections missing. But, was I worried? Nope, and I’ll tell you why in my latest garden video.

Has this happened in your garden? What plants were affected?

A few weeks ago, I had the opportunity to take another photo of a landscape I passed by in a neighborhood where I had just finished up a landscape consultation.

Sadly, I often see examples of truly ‘interesting’ or should I say ‘bad’ pruning.  I drove by this landscape and then made a U-turn so that I could take a quick photo…

Shrub pruning

Shrub pruning

I don’t know about you, but these Texas sage shrubs look like mushrooms, don’t you think?

Sadly, pruning these beautiful flowering shrubs this way robs them of their flowers, increases maintenance, creates dead wood, and shortens their life.

While there are quite a few shrubs that take well to repeated formal pruning – doing this to flowering shrubs should be avoided.

I must admit that I have seen Texas sage and other flowering shrubs pruned into many different shapes…

But, let me be frank – shrubs aren’t meant to be cupcakes, frisbees, or gumdrops

Here are just a few reasons why…

  • It removes the leaves needed for the shrub to make energy for itself
  • Excessive pruning actually makes your shrubs grow faster, which equals MORE maintenance
  • Shrubs pruned often require more water as they constantly work to replace foliage lost
  • Continued shearing will shorten the lifespan of your shrubs
  • Green ‘blobs’ are ugly compared to beautiful flowering shrubs

If you are tired of the time and money it takes to maintain flowering shrubs the ‘wrong’ way. I invite you to join me in my online shrub pruning workshop where I will teach you the right way to prune.

Imagine your outdoor space filled with beautiful, flowering shrubs instead of green ‘balls’. Believe it or not, the shrubs in the photo above are the SAME plant – they have just been maintained differently. The one on the left takes much more money and time and the other thrives with pruning once (or twice) a year.

In my online class, I show you how to work with your landscaper or how you can take care of your shrubs yourself. Got ‘green balls’ already in your landscape? I’ll teach you how to rejuvenate them and the best time of year to do it.

So, ditch the ‘green blobs’ in your yard and learn how to prune with confidence – it’s much easier than you think. Learn more here and what students have to say about the class.

When people think about what a desert garden looks like, what comes to mind? Perhaps, visions of lots of brown with rocks and a cactus or two?

While you can settle for rocks and some cacti, the truth is, we can have so much more! Imagine a landscape filled with the colors of the rainbow – shades of red, orange, purple, pink, and yellow.

I’m going to share with you 8 colorful plants that you will find in my desert garden. All are colorful and thrive in a hot, dry climate:

Colorful Plants for Desert Garden

Colorful Plants for the Desert Garden

Bougainvillea – Bougainvillea ‘Barbara Karst’

You can’t beat Bougainvillea for the vibrant color in the garden. It thrives in our dry, hot climate and flowers off and on spring through fall. Record-breaking heat doesn’t bother it in the least. It is a great choice for covering a bare block wall and can handle those challenging west-facing exposures. For maximum flowering, they need to be in full sun. For those that don’t like the messy flowers, you can opt for dwarf varieties or plant one in a large pot, which will limit its size.

Hardy to 20 degrees F. Plant in full sun for optimal flowering.

Colorful Plants for Desert Garden

Coral Fountain – Russelia equisetiformis

Often referred to as Firecracker Bush, this tropical beauty has a lovely cascading growth habit. Arching stems produce orange/red tubular flowers that delight hummingbirds. Blooming occurs spring through fall. This shrub takes a year or two before really taking off, but it’s worth the wait – I like to use them in groups of 3 to 5. It is also a good choice for adding to large containers – especially blue ones!

Cold hardy to 10 degrees F. Plant in full sun.

Colorful Plants for Desert Garden

Firecracker Penstemon – Penstemon eatoni

Winter color is often lacking in desert gardens. However, there are many plants that offer color through winter. This western native is my favorite during winter and spring in my front garden when it burst forth with brilliant orange/red blooms. Hummingbirds really enjoy the blooms as there aren’t many other plants for them to feed on this time of year. Prune off spent flowering stalks once the flowers begin to drop and you may get another flush of blooms to extend the season. It can be hard to find Firecracker Penstemon in box stores but local nurseries usually carry them.

Hardy to -20 degrees F. Plant in full sun.

Colorful Plants for Desert Garden

Yellow Bells – Tecoma stans var. stans

Admittedly, there are many yellow-flowering plants in the desert, but this one is my favorite! I look forward to the gorgeous yellow blooms opening each spring in my back garden. Yellow bells bloom spring through fall, and hummingbirds are attracted to their flowers. They are fast growers and have lovely, lush green foliage. To keep them looking their best, prune them back severely to 1-2 feet tall once the threat of frost has passed in spring. There are several notable varieties of Yellow Bells in shades of orange including ‘Crimson Flare’ and ‘Sparky’.

Hardy to 10 degrees F. Plant in full sun to filtered sun.

Shrubby Germander – Teucrium fruticans ‘Azurea’

Photos don’t do this Mediterranean native justice. When viewed in person, people are immediately transfixed by the light-blue flowers (they appear more purple in photos), which appear in spring. I have several scattered throughout my back garden, and for me, they bloom throughout winter too! Using plants with silver-gray foliage near those with darker green leaves is a great way to add interest to the landscape, even when not in flower. I dearly love this shrub for its colorful winter/spring blooms in my desert garden.

Hardy to 10 degrees F. Plant in full to filtered sun.

Purple Lilac Vine – Hardenbergia violaceae

Here is another winter-flowering beauty. Purple flowers cover this vine from February into early March. Believe me when I say that they are a welcome relief to the winter blahs. Bees enjoy the blooms, which resemble lilacs but aren’t fragrant. It does require a trellis or other support to grow up on. When not in bloom, its attractive foliage adds a welcome splash of green throughout the year on vertical surfaces. The Purple Lilac vine is usually found in nurseries in fall and winter, during its flowering season.

Hardy to 20-25 degrees F. Plant in full to the filtered sun but avoid west-facing exposures.

‘Rio Bravo’ Texas Sage – Leucophyllum langmaniae ‘Rio Bravo’

If you love the color purple, you’ll want to include this variety of Texas Sage in your garden. Branches covered in masses of purple flowers appear off and on spring through fall, often in response to periods of increased humidity. The more humidity, the more flowers produced. There are many different types of Texas Sage and all add color to the desert garden. Now, you may not see them looking like this for the sad fact that many people prune them into unnatural shapes like balls, cupcakes, and even squares. Which would you rather have – a green ‘blob’ or a gorgeous purple beauty like this?

Hardy to 10 degrees F. Plant in full sun for maximum flowering.

Desert Willow – Chilopsis linearis

I want to include a tree in our list of colorful plants for the desert garden. Desert Willow is small to medium-sized tree that are native to the Southwest. Throughout the warm season, branches with bright green leaves are covered with pink blooms. The flowers add a lovely shade of pink, which is a color not always seen in the desert. There are many newer varieties of Desert Willow – I have four different ones in my garden, but ‘Bubba’ is my favorite. This is a deciduous tree and will lose its leaves in winter. 

Hardy to -10 degrees. Plant in full sun.

SO, where can you find these plants?

I am often asked where is the best place to buy plants. Yes, you can head to your big box store, but they usually lack variety and are known to sell plants that don’t do well in our hot, dry climate.

My advice is to look to your local garden center and nursery for these and other plants for your garden. 

I’d like to share with you about a new nursery that is mixing things up in a good way! Four Arrows Garden is a family business, located in Vail, AZ, where you order your plants online and they deliver them to you!

The Chavez family began their business with cuttings from succulents in their backyard that soon grew to people wanting them to offer other types of plants. She explains their unique nursery, “Our business model has changed over the year to fill the need in our community. We have transformed into “not your average nursery” because of a niche market to deliver landscape plants and creating an online shopping outlet for desert-adapted plants. We are different because we allow customers to shop for plants from the comfort of their homes.”

They source their plants from wholesale growers in the Phoenix and Tucson area. While their delivery area is primarily in the greater Tucson area, They can accept special requests from Phoenix area customers.

I encourage you to incorporate colorful plants within your desert garden to improve your curb appeal and your enjoyment of your outdoor space. Local nurseries are the best sources for these plants. If you are in the Tucson area, visit Four Arrows Garden’s online nursery to make your special order and they will deliver it to your door. Check them out on Facebook where Linsay keeps you updated on the latest plants available!

Aren’t these shrubs beautiful?

‘Rio Bravo’ Sage (Leucophyllum langmaniae ‘Rio Bravo’)

You would think that the beauty of these shrubs, in flower, would be enough for people to stop pruning them into absurd shapes, but sadly, this is not the case. In the Desert Southwest, there is an epidemic of truly horrible pruning that affects not only Texas Sage (Leucophyllum species), but also Cassia (Senna species), Fairy Duster (Calliandra species), and even Oleander.

Unsurprisingly, excessive pruning like this is NOT healthy for shrubs and it strips them of their beauty.

You don’t have to go far to see these sad shrubs. All you need to do is drive down the street as I did…

flowering shrubs need pruning

Okay, it should be rather obvious, but I will say it just the same,  “Do not prune your shrubs into the shape of a ‘frisbee’.

I kept driving and found even more examples of truly awful pruning.  Sadly, all are within a 5-minute drive of my house.

pillbox

I call this ‘pillbox’ pruning. These Texas Sage & Cassia shrubs were located across the street from the ‘frisbee’ shrubs.

Leucophyllum frutescens 'Green Cloud

An attempt at creating a ‘sculpture’? Texas Sage ‘Green Cloud’ (Leucophyllum frutescens ‘Green Cloud’)

 A second attempt at creating a sculpture?

Let’s get real. Shrubs pruned this way does nothing to add beauty to the landscape. And, when pruned this way, they cost more, take more time, and use more water – it’s true!

Now on to some of my favorite ‘cupcake’ examples:

Leucophyllum frutescens 'White Cloud

An entire line of ‘cupcakes’. ‘White Cloud’ Texas Sage (Leucophyllum frutescens ‘White Cloud’)

Do you think they use a ‘level’ to make the tops perfectly flat? I honestly wouldn’t put it past them.

flowering shrubs need pruning

You can see the dead area on the top, which is caused from this shrub being sheared repeatedly.

flowering shrubs need pruning

This dead growth is caused by lack of sunlight.  Repeated shearing (hedge-trimming) keeps sunlight from reaching the interior of the shrub.   As a result, branches begin to die.

After driving around for a while, I drove toward home when I saw the saddest ones of all…

flowering shrubs need pruning

 Now if you look closely, you can see a light layer of gray-green leaves, which really don’t begin to cover the ugly, dense branching that has been caused by years of repeated shearing.

Texas Sage

 I actually like topiary, but not when done to a Texas Sage. Some people prune up their shrubs so that they can clean up the leaves underneath more easily.

Now, I am not against formal pruning, when performed on the right plants. But, it is not attractive when done on flowering, desert plants and it is also unhealthy for the shrubs themselves and contributes to their early death in many cases.  Add to that the fact that it greatly increases your maintenance costs due to repeated pruning and having to replace them more frequently.

Now if you have shrubs that look like any of these pruning disasters, don’t panic! They can be fixed in most cases.

flowering shrubs

 Now, why would anyone want to remove the flower buds from your shrubs by shearing,  when you can have flowers like this?

If you are tired of unnaturally shaped shrubs in your landscape, I understand. Believe it or not, most flowering shrubs need pruning once or twice a year at most – and NOT the type of pruning into weird shapes. I find it ironic that your yard will look better when you do less.

flowering shrubs

So, if you are wanting to declare your landscape a ‘cupcake-free’ zone, I have something I think you’re gonna love. I invite you to check out my popular online shrub pruning workshop where I teach you how to maintain flowering shrubs by pruning twice a year or less. Hundreds of students have taken the course and are reaping the rewards of a beautiful outdoor space filled with colorful shrubs at a fraction of the work.

Are you ready to break out of the cycle of green blobs?

Desert Garden heat with little fuss.

Let’s face it. Hot summers are not surprising to desert dwellers. In fact, a typical desert garden with native and desert-adapted plants will weather intense heat with little fuss.

However, this summer has been one for the books and I’ve seen signs of heat-stress that I’ve never seen before. And yes, within my own garden.

Heat-stressed Rock Penstemon and Golden Barrel Cactus

I must admit that it’s been hard to see certain plants struggling in my desert garden and I know you may have similar feelings. So, why has this summer been so much more difficult than others?

Pink Trumpet Vine partially defoliated due to the heat in desert garden

Pink Trumpet Vine partially defoliated due to the heat

While it is normal to have several days above 110 degrees F., the summer of 2020 is one for the record books. We have experienced not just a couple of stretches of above-normal temps but, several long spans of infernal heat. Damage to plants is often cumulative. This means that the more days of above-average (or below-average) temperatures – the higher incidence of reaction from plants.

Take a walk outside in your garden. You will likely notice some plants that are yellowing, wilting, or have given up and died. However, you may also note that there are some that are doing well.

Why is that? Let me show you some examples from my own garden – the good AND the ugly.

Let’s start with the ugly:

New Mexican Fence Post cactus transplants desert garden

New Mexican Fence Post cactus transplants

In March, much of my backyard was renovated. This included the addition of two separate plantings of Mexican Fence Post cacti. They are located along my back wall and as you can see, one is doing very well while the other makes me cringe when I see the yellowing.

Does the yellowing cactus need more or less water? No. Many succulents yellow in response to summer heat. Of course, this very hot summer has made it more severe. So, why the difference between the two?

The one on the left gets filtered shade in the afternoon from a nearby Palo Verde tree. You can tell that the one on the right doesn’t get any shade but full afternoon sun. In a normal summer, it would be normal to see some yellowing that will return to green once temperatures cool. I am hopeful that will happen. As plants age, they tend to handle heat stress better and as these are young, the stress was especially severe.

Signs of heat stress desert garden

Signs of heat stress

In another area of my garden, I have Green Desert Spoon and Hardy Spineless Prickly Pear, which are very heat-adapted. Yet, they do show signs of mild heat-stress that I haven’t seen before. But, they will green back up in fall. Other plants that are struggling include Artichoke Agave, Gopher Plant, and Shrubby Germander.

I am thrilled that my young Desert Willow tree in this photo is thriving despite the heat. I have four others scattered throughout my landscape and all are doing just as well.

Here are some of the good:

There are still six weeks of summer heat ahead of us. So, what should we do for now?

  1. Be sure plants are receiving enough water. You may need to increase the frequency when temps are above 110 degrees.
  2. Don’t fertilize. Feeding plants simply makes them work harder to produce new growth when all they are trying to do is deal with the heat.
  3. Don’t prune away heat-damaged growth until September. While brown leaves are ugly, they are protecting the interior of the plant. Some pruning is recommended in mid-September, which I teach in my Shrub Pruning Workshop.

We don’t know if this summer will be an anomaly or the beginning of a new normal. But, instead of throwing in the towel, I invite you to do the following instead:

Take a stroll through your garden and take note of which plants are doing well and those that aren’t. If this is to be the new norm, it would be a good idea to add more of those that handle the heat well.

desert garden

I am not going to make any major changes in my own garden. Most of my plants have done just fine in past summers. I’ll replace the few plants that died but am hopeful that next summer will be one with average temperatures. If not, then I know what plants have withstood the heat best.

Before we know it, fall will be here, and I for one, can’t wait!

Gorgeous Germander for Desert Gardens

To Do About Aphids

What do you do when you spot aphids on your plants?

Do you reach for the nearest bottle of insecticide? Spray them off with a hose or remove them with your fingers?  

Believe it or not, sometimes the best thing is to do nothing.

So, is this something I learned in school? No. I figured it out by observing the plants in my first garden.

To Do About Aphids

I remembered this early lesson when I passed by a severely pruned oleander shrub in front of my favorite bagel shop.  

To Do About Aphids

The oleanders were growing back nicely. However, there were yellow aphids on the young leaves.

Years ago, my oleander shrubs had an infestation of yellow aphids like this, and I was anxious to get rid of them. Really, this is our first reaction when we see bugs on our plants – we want them gone.

I had several methods at my disposal – insecticidal soap, a strong jet of water or my fingers – all of which, would help get rid of most of the aphids. But, life got in the way, and I didn’t have a chance to get out to treat my shrubs until about ten days later.  

Can you guess what I found?  Not a single aphid.  I didn’t have to do a thing, and the aphids were gone, and my shrubs look great.

So, what happened to the aphids?

When harmful insect pests first appear, it can take a week or two before their natural predators follow. In the case of aphids, lacewing and ladybugs showed up and ate the aphids.  

To Do About Aphids

Plants are tougher than we give them credit for and can handle a certain amount of insect pests without any adverse effects.  

So, when I come back in a couple of weeks to the same bagel shop, I expect to see no aphids in sight and a healthy oleander shrub.

The lesson here is that you don’t need to freak out when you see aphids as the normal cycle of nature will take care of them. However, you can step in to get rid of them if you see adverse effects on plants such as wilting, smaller blooms, or discoloration.

No matter where you live, you will see the same shrubs being used over and over again in countless landscapes. While the shrubs may be attractive, their overuse throughout neighborhoods creates a boring appearance because they are so common.

oleanders

In California, Nevada, and Arizona, oleanders have held a prominent spot in the landscape for years. Their popularity is due to their lush evergreen foliage, ability to withstand intense heat, and their pretty flowers.

However, their overuse in many areas makes their beauty less impactful and frankly, almost forgettable.

 At a recent conference, this point was put quite succinctly by the head of horticulture for Disneyland who said,

“When things are expected (in the landscape), they become less powerful and impactful”.

His statement sums up what happens when we use the same plants over and over.

In the case of oleanders, there is another problem.

Oleanders

Oleanders are susceptible to a fatal disease called, oleander leaf scorch. This disease has come from California into Arizona where it is popping up in neighborhoods in Phoenix and also Lake Havasu. I have consulted with several cases affecting large, mature oleanders in Arcadia, Biltmore, and Moon Valley areas in Phoenix. 

This bacterial disease is spread by leaf-hopper insects and there is currently no known cure or control available. Infected oleanders slowly decline over 2-3 years before dying. To date, dwarf oleanders have not shown signs of the disease, only the larger forms. But, that could change sometime in the future.

Objectively, there’s a lot to like about oleanders; they thrive in hot, dry climates with minimal fuss, have attractive dark green foliage, and add color to the landscape when in flower. However, their overuse in the landscape makes them less impactful and coupled with their susceptibility to oleander leaf scorch, people want an alternative. 

You can learn more about this disease that affects oleanders here.

Hop Bush: 

Hop Bush

When asked for another option for the large, tall forms of oleanders, I recommend Hop Bush (Dodonaea viscosa), also known as Hopseed Bush.

Grab my FREE guide for Fuss-Free Plants that thrive in a hot, dry climate!

This native desert shrub has attractive, evergreen foliage and a similar growth habit to oleander. They grow up to 12 feet tall or prune to a shorter height.

Hop Bush

Use Hop Bush in the same ways as oleanders to provide a nice green hedge or privacy screen.

Hop bush flower

While they don’t have colorful flowers; they have lovely foliage that is only mildly poisonous as opposed to oleanders which are highly toxic.

Hop bush

Hop bush has a lovely natural shape or prune as a formal hedge.

Want to learn more about this oleander alternative? In my latest Houzz article, I share what types of plants look nice next to hop bush, how to care for them and show a purple-leaf form.

I hope that you find a spot for this lovely shrub in your landscape.

Have you ever seen hop bush growing in the landscape?  

Gardeners have long known about white flowers plants and the beauty that they bring to the garden.

The color white is seen by many as a bright, clean color that makes surrounding colors ‘pop’ visually.  Others like how white flowers seem to glow in the evening and early morning hours in the landscape.

Thankfully, there are several white flowering plants that do very well in the Southwestern landscape. In Part 1, I showed you four of my favorites, which you can view here.

Today, let’s continue on our white, floral journey…

Disclosure: Some of the links below are affiliate links, meaning, at no additional cost to you, I may earn a commission if you click through and make a purchase.

White Evening Primrose (Oenothera caespitosa)

White Evening Primrose (Oenothera caespitosa)

The arrival of spring transforms the low-growing green foliage of White Evening Primrose with the appearance of beautiful white flowers. What makes these flowers somewhat unique is that as the flowers fade, they turn pink.

White Evening Primrose looks best when used in a landscape with a ‘natural’ theme or among wildflowers.

The flowers appear in spring and summer on 10″ high foliage.  Hardy to zone 8 gardens, this small perennial is native to Southwestern deserts.

White Globe Mallow (Sphaeralcea ambigua 'White')

White Globe Mallow (Sphaeralcea ambigua ‘White’)

This is a shrubby perennial that is in my own landscape.  While the most common color of Globe Mallow is orange, it does come in a variety of other colors including red, pink and white – all of which I have.

The white form of Globe Mallow shares the same characteristics of the orange one – it thrives in full sun and can even handle hot, reflected sun.  The foliage is gray and looks best when cut back to 1 ft. high and wide after flowering in spring.

I pair white Globe Mallow alongside my pink ones for a unique, desert cottage garden look.

White Flowers for the Southwest

See what I mean about white flowers helping other colors to stand out visually?

Hardy to zone 6, Globe Mallow grows to 3 ft. tall and wide.  It does best in full sun and well-drained soil.

Blackfoot Daisy (Melampodium leucanthum)

Blackfoot Daisy (Melampodium leucanthum)

Blackfoot Daisy is another perennial that looks great in a natural desert-themed landscape.  This ground cover produces sunny, white daisies in spring and fall in desert climates – it flowers during the summer in cooler locations.

Hardy to zone 5, Blackfoot Daisy can handle extreme cold when planted in full sun.  I like to plant it near boulders where it can grow around the base for a nicely designed touch. It grows to 1 ft. high and 24 inches wide.

I have several in my front garden and I love their beauty and low-maintenance. They need very little maintenance other than light pruning with my Felco Hand Pruners in late spring to remove dead growth.

Little Leaf Cordia (Cordia parvifolia)

Little Leaf Cordia (Cordia parvifolia)

This white flowering shrub is not used often enough in the Southwestern landscape in my opinion.  It has beautiful flowers, needs little pruning if given enough room to grow, is extremely drought tolerant and evergreen.

Little leaf cordia can grow 4 – 8 ft. tall and up to 10 ft. wide. Unfortunately, some people don’t allow enough room for it to grow and shear it into a ‘ball’.

You can go 2 – 3 years or more between prunings. It’s best when left alone to bear its attractive, papery white flowers spring into fall.

Hardy to zone 8, little leaf cordia does great in full sun and well-drained soil.

‘White Katie’ Ruellia (Ruellia brittoniana ‘White Katie’)

During a visit to a nursery some time ago, I noticed a white flowering variety of the more commonplace purple ‘Katie’ ruellia and I immediately decided that I liked the white color better.

‘White Katie’ ruellia grows to 8 inches tall and 1 1/2 ft. wide in zone 8 gardens and warmer.  It looks great when planted in groups of 3 or more.  You can plant it alongside the purple variety for fun color contrast.  It does suffer frost damage when temps dip below freezing but recover quickly in spring.  

This white flowering perennial does best in morning sun or filtered shade in desert gardens.

I hope you have enjoyed these white flowering plants and decide to add them to your garden!
