Discovering the Beauty of the Purple Lilac Vine (Hardenbergia violacea)

In the midst of a colorless winter garden, a burst of vibrant beauty can be a delightful surprise. Explore the wonders of this wonderful purple vine, a lesser-known gem that thrives in the desert garden.

Embracing the Lilac Vine’s Versatility

Welcome to the world of the purple lilac vine (Hardenbergia violacea), an Australian native cherished for its unique charm. While it’s not a true lilac, it serves as a wonderful substitute in regions like the low desert where traditional lilacs struggle to grow. Regular irrigation is important.

A Versatile Beauty

This versatile vine can be employed in various ways in your desert southwest garden. Traditionally used as a vine, it can also shine as a ground cover, as my experience from over 20 years ago demonstrated. Its adaptability is one of its key strengths.

Blooming in the Heart of Winter

One of the most remarkable attributes of the lilac vine is its winter bloom. In zone 9 gardens, February brings forth a profusion of gorgeous purple flowers, adding a touch of elegance when little else is in bloom.

Isn’t it beautiful?

This Australian native is known by different common names with lilac vine (Hardenbergia violacea) being commonly used in our area of the Southwest.

It is not actually a lilac, but because we cannot grow lilacs in the low desert, this is a wonderful substitute.

My first experience using Purple Lilac was over 20 years ago when I used it in a feature area on one of the golf courses I worked for.

Although traditionally used as a vine, I used it as a ground cover; believe it or not, it did beautifully.

One of the best attributes of this vine is that it blooms during the winter month of February in our zone 9 gardens.

Now be honest, there is not much going on in your garden in winter, is there? Wouldn’t it be great to have gorgeous purple flowers blooming when little else is?

Reasons to Welcome this Winter Vine

Here are more reasons to consider introducing this lovely vine into your garden:

  • Winter Blossoms: Brighten up your garden during the colder months.
  • Year-Round Attractiveness: Even when not in bloom, the vine boasts appealing foliage.
  • Low Maintenance: Minimal care required; occasional pruning for size control and little need for supplemental fertilizer.
  • Vertical Growth: It thrives when provided with a trellis or support structure.
  • Ideal Placement: East or south-facing areas are especially suitable for this vine.
  • Hardiness: Hardy to USDA Zone 9, it withstands typical winter temperatures but may suffer frost damage in the upper 20s°F.

Under normal winter temperatures, it doesn’t suffer frost damage.

Purple Lilac Vine Has Useful Appeal

The vine isn’t just about looks. It can serve as a decorative asset, transforming bare walls and concealing unattractive views with its lush foliage and vibrant blooms.

When people ask me if I recommend a particular plant, I tell them that the highest recommendation that I can give is is if I have that plant growing in my garden.

I do not have the patience to grow a plant that struggles and/or takes too much maintenance.  It also has to look beautiful most of the year.

So if you ask me if I truly like this vine, I answer by saying that I have four growing in my backyard 🙂

Sourcing Your Purple Lilac Vine

While some may struggle to find this vine in local nurseries, fret not. Most nurseries typically stock them when they’re in full flower during the winter. It’s important to note that while the flowers resemble lilacs, they may not be strongly fragrant. However, their sheer beauty makes up for any lack of fragrance.

Discover the magic of this wonderful vine and infuse your winter garden with a burst of captivating color and charm. Happy gardening!

Understanding the Mystery of Dead Plants

I’m pretty sure I know the answer to the dead plant mystery.

We have all likely experienced the death of a plant in our garden, and even though I am a horticulturist, I’m not immune.

Sometimes, plants die in my garden too.

The Perplexing Case of ‘Blue Bells’ Emu Bush

Here is a photo of my recently deceased ‘Blue Bells’ emu bush.

I was surprised to see that it had ‘kicked the bucket’ as its nearby neighbors were flourishing. Dead plants can tell a story.

So, the question I have to ask myself is, why did it die?


How to Figure Out Why a Plant Died in Your Garden

To determine why a plant died, here are some things to ascertain…

1. Recent Planting and Transplant Shock:

Was it planted recently? If so, it may not have had enough time to grow enough roots to survive summer. Transplant shock is a real thing.

2. Watering Issues Are a Concern:

Did it get enough water? Was the drip emitter plugged or broken? Sometimes we need to better educate ourselves on water irrigation.

3. Sun Exposure Extremes:

Was it planted in the wrong exposure? In other words, did it get too much sun or not enough? Both of these things can cause dead plants.

4. Climate Compatibility Can Cause Dead Plants:

Does the plant do well in our hot, desert climate? Or will it end up a dead plant because it is not built for the desert climate.

5. Pest Problems:

Were there any pest problems, such as ants around the roots or other unwelcome bugs? This can weaken the plant.

6. Overall Landscape Health:

Are identical plants in your landscape struggling too? If so, they might all be struggling due to a similar issue.

7. Soil Conditions are Important:

Is there a problem with the soil? Groupings of dead plants can sometimes indicate poor soil conditions.


Using these questions as guidelines, you’ll likely have the answer to why a plant has died.

However, in my case, the plant was a few years old, always did well, and the ‘Blue Bells’ nearby were thriving.

So, why did it die?

I don’t know…

Sometimes plants die, and we don’t know why. I realize this can be hard to accept without having the answer.

That is what happens in nature – things die, and we don’t always have the answers as to why.

In my particular case, I am replanting a new “Blue Bells” because I know it grows well for me in this spot. I ensured there were no unwelcome bugs in the soil and amended the soil with 1 part compost mixed with 1 part existing soil to give it a little ‘boost.’ You might find a different plant that works well for your garden.

I hope my new plant is happy…

Protecting Your Desert Garden From a Heatwave

Protecting Your Desert Garden From a Heatwave

Summers in the desert garden is hot. That’s no surprise. However, there are periods within these hot months when temperatures climb higher than normal. Because of this, we do need to help protect our gardens from the effects of a heatwave.

So, what is considered a heatwave in the low to mid-altitude desert? As a rule, when the mercury edges above 110 degrees F. During a heatwave, they can even go close to 120 degrees – ouch!

Thankfully, there are things you can do to help prepare the plants within your garden right now.

Here is my #1 tip…

Water your plants deeply the night before three – four day span of 110+ degree are forecast. This is in addition to your regular drip irrigation schedule.

The goal of this supplemental irrigation is to water deeply. This allow the soil to stay moister for longer, which will benefit your plants.

Under normal circumstances, I water my plants for 1 1/2 hours. However, in preparation of a heatwave, I water 2-3 hours. Plants will need more water in order to deal with the extreme temps and the extra water that will be lost to the atmosphere through their leaves.

Don’t do this every night, only every 4 days or so during a heatwave.

My second piece of advice…

Provide temporary shade for young plants in your landscape as they are more susceptible to stress from a heatwave.

This is because they don’t have a well-established root system to uptake much water and sparser foliage, so there aren’t many leaves to shade other parts of the plant.

Shade cloth is useful for protection lasting over several months. But for short-term shade during a heatwave, you can use burlap, sheets, an umbrella, or even place a patio chair over a susceptible plant. Uncover plants once temperatures are within the normal range.

Hot temperatures are a fact of life during the desert summer as are heatwaves. But, implementing one, or both, of these tips will help the plants in your garden.

We met at her house early in the morning with the filmmaker who set up the cameras and microphones. Our host is one of the most gracious people I know and kept us warm with the outdoor fireplace and feeding us donuts 🙂

I love talking about desert gardening

Being interviewed – I love talking about desert gardening!

Lights, Camera, Desert!

We spent about 3 hours there with me talking about the unique challenges and possibilities of gardening in a hot, dry climate. During the filming, I walked around the garden, highlighting different areas throughout the garden. This garden has many ‘rooms’ and corners that display the beauty of winter in the desert.

The video has come out, and I’m so happy at how well the folks at Plant Pop condensed our visit into a 4-minute video so nicely.  I hope you enjoy it and come away inspired by what you can do in your own desert garden!

A Stroll Through a Flowering Winter’s Garden

“How much water do my plants need?”

I am often asked this question by desert dwellers and my answer is always, “That depends.”

desert-landscape

There are several variables that determine how much water plants need, along with the frequency of watering.

Variables include:

  • Type of soil (clay, sand, combination)
  • What kind of plant (native plants, higher water use flowering shrubs and ground covers, succulents, etc.)
  • Recommended depth of water
  • Desert region (low-desert, mid-altitude, high desert)
  • Efficiency of irrigation system
  • Water pressure (can vary between neighborhoods)

As you can see, there is no universal watering guideline in regards to how long to water or how often.

Let’s look into the variables a little more closely to help you determine what yours are:

Soil – Clay soils hold onto water longer than sandy soil. They take longer for water to permeate to the recommended depth. The result? Clay soils need irrigation less often than sandy ones but need to be watered for a longer length of time. Phoenix area soil tends to have more clay in them while those in the Palm Springs area are sandy.

Plants – Native or desert-adapted plants need less frequent irrigation versus those that come from tropical climates. Cacti and other succulents do well with infrequent irrigation.

Water Depth – Trees need to be watered deeply while ground covers and succulents do fine at a more shallow depth – shrubs fall in between the two.

Desert Region – Where you live in the desert matters when it comes to water and your plants. The differences include rainfall amounts, when the rain falls, high and low temps, and more. Residents of low-desert cities like Palm Springs and Phoenix need to add water to their plants more often than those who live in higher elevation regions such as Tucson.

Irrigation System – The older your irrigation system, the less efficient it is. This is due to mineral build-up within the system, which affects the amount of water that comes out. Also, old drip irrigation systems tend to accumulate leaks. The average lifespan for a drip irrigation system is 10-15 years. 

Despite these differences, what is a shared characteristic is that the vast majority of desert residents water too often and not deeply enough. This is usually due to lack of knowledge and thinking the ‘more is better,’ especially in the desert.

Landscapers are generally not a reliable source when it comes to scheduling irrigation – most recommend irrigating far too often.

So what is a desert dweller to do?

Thankfully, there is very useful information available for homeowners to help them figure out when and how much water their landscape needs.

Major metropolitan areas throughout the Southwest have excellent watering guidelines available for residents. The guidelines include the regional variables we have discussed so far.

Here are helpful links based on major desert cities (click the link for the city closest to you):

Las Vegas

Palm Springs

Phoenix

Tucson

Watering guidelines are just that – guidelines. Circumstances may mean that you need to water more or less often, but these guides are a useful baseline to work from.

*One final note – before you implement a new irrigation schedule, it’s important to gradually wean your plants to the new one over several weeks. The reason for this is that it allows plants to become accustomed to the new schedule.

Yes, it does take a little work to figure out how much and often to water your plants, but these guides are incredibly helpful and will guide you along the way.

Unwanted Guests: Dealing with Javelina in Your Desert Garden

Yesterday, I had a rather unexpected encounter with a javelina while taking pictures of a landscape. I think he was as surprised as I was to see him and he retreated back to his arroyo after a couple of minutes. That meeting inspired me to write this post and how they affect the desert garden – primarily what types of plants they like to eat.

Javelina: The Surprising and Destructive Garden Visitors

To state that I was surprised to come so close to a javelina is an understatement. In the over twenty years that I’ve worked in desert gardens, I seldom see these pig-like mammals as they usually sleep through the day underneath mesquite or other desert trees.

Understanding Javelina and Their Habits

Often referred to as ‘wild pigs’ due to their resemblance to a boar, they aren’t pigs, but are a peccary, which is a medium-sized mammal with hooves. Javelina are found throughout the Southwest, but their range also extends to Central and South America. In urban settings, you’ll find them in more naturalized areas.

Plants Javelina Love and Those They Leave Alone

They frequently travel in herds, although I only saw these two adults on this day. While it can be enjoyable to view them from afar (don’t get too close as they can be dangerous), dealing with the damage that they cause to gardens isn’t fun.

Javelina’s Dietary Preferences

Javelina love to eat the pretty things we plant in our desert landscapes such as flowering annuals, and they don’t stop there. The spines on your prized cactus won’t deter a hungry little animal – they go right in and munch on the base of a prized columnar cactus as well as the pads of prickly pear cactus.

When surveying the damage that they cause to the garden, what makes it worse, is that the pig-like critters frequently don’t eat what they dig up.

1. Petunias and flowering annuals are delicious

Plants on a golf course

My relationship with these wild animals is a long one. It began by working to keep them away from the thirty-six tee boxes that I had to plant with flowering annuals seasonally on a golf course. Not surprisingly, they were drawn to these colorful petunia and annual islands and would dislodge the plants by rooting them up with their snouts before eating them.

My crew and I had some mixed success with spraying squirrel repellent every few days on the petunias, but it was a lot of work and not foolproof.

2. Soft leaved plants are Javelina candy

geraniums and annuals in a container

Javelina will zero in on popular potted annuals such as pansies, petunias, snapdragons, which are like candy to them. While geraniums aren’t their favorite potted flower, they will eat them too if hungry enough. They prefer soft leaved plants.

If you want pretty containers filled with flowers and live in a neighborhood where javelina are present, you’ll need to place the pots in an enclosed area or courtyard where they can’t reach. 

3. Citrus and seed pods attract the desert peccary

Depending on the time of year, a javelina’s diet changes, based on what is available. In winter, citrus they will grab citrus fruit off of the tree.

In summer, mesquite seedpods are one of their favorite foods.

4. Cactus of all kinds feed the peccary

A fairly common sight is a columnar cactus with some bites taken out of its base. This can happen where packs of the animals are present. In most cases, the damage is largely cosmetic and the cactus will be fine. However, to prevent further damage, you can surround the base of the cactus with a wire mesh cage.

Prickly pear cactus is another plant which is devastated by the cactus loving desert dweller.

Protecting Your Garden: Tips for Javelina-Resistant Plants and Fencing

While there is no guarantee that these animals won’t eat the plants in your desert garden from time to time. There are some plants that are less palatable to them than others. Here a helpful link for javelina resistant plants. I must tell you that if a a wild animal is hungry enough, it will eat the plants on this list – I know this from personal experience. 

The only foolproof way to keep them away from eating your plants is to keep them out with a fence or wall.

September Gardening Tasks

September Gardening Tasks

After a seemingly endless summer, we have finally made it to the finish line.  This is the season where we experience a ‘second spring’ and venture out into the garden again.

September is the gateway to a busy time in the garden, but there are a few things that it is still too early to start on yet.

I’ve made a video of what you should do and shouldn’t do this month:

 
 
 

What is your favorite season of the year?

Easy Garden Project: Create a Hummingbird Haven in a Container

It never ceases to amaze me how that despite how busy your calendar, everything grinds to a halt when you get sick.  Oh, I realize that there are certain types of sickness that you can press on through like a cold or even a small fever.  But, when the stomach flu hits, you are powerless to do anything.

What makes it worse is when everyone in your household gets it as well.  So, we have been spending quality time together nursing our sore stomachs and anxiously awaiting the time until our appetites return.

In the meantime, the garden is undergoing some contruction.

new drip irrigation installed

Irrigation trenches are criss-crossing our landscape as we are having new drip irrigation installed.  Our current system was first installed when we built our home 18 years ago and was having problems with numerous leaks.  Considering that the typical lifespan of a drip irrigation system is 10 – 15 years, we were long overdue to have ours replaced.

While it may not seem very exciting, I am looking forward to having separate drip lines for my fruit trees, shrubs/perennials and vegetable garden.

Many plants in my garden are beginning to bloom adn I thought I would give you a peek.

The seeds are from Botanical Interests and are called ‘Fairy Bouquet’ toadflax.

'Vanilla Berry'.

Another plant that has started blooming is from Renee’s Garden seed company and is called ‘Vanilla Berry’.

So far, these are the only two types of plants flowering in this garden, but the California poppies are getting ready to burst forth in different colors including white, purple, pink and of course, orange.

Citrus trees are also in full bloom perfuming the air with their intoxicating fragrance.  I am hopeful that my young Meyer’s lemon tree will produce its first lemons.

The peach trees bloomed earlier this year and are now filled with immature peach fruit – I can almost taste the peach jam that I will make from them this May.

Spring Flowers, Lobelia

The cool-season annuals that I planted in the fall are still going strong.  Even though they look great right now, I will replace them later this month with warm-season annuals in order to allow them time to grow a good root system before the heat of sumemr arrives.

Salvia greggii

Late winter and spring is also when my autumn sage (Salvia greggii) is also in flower.  I received several different varieties, straight from the grower, to try out in my garden, which were planted last fall.  They are doing great in their current location where they receive morning sun and afternoon shade.

On another note, we have been anxiously awaiting the re-emergence of our desert tortoise, Aesop.

Stomach Flu and Spring Flowers

We last saw him in late October before he went into his hole to hibernate.  Since then, we’ve periodically checked on him and today, we moved slightly.  So, I can’t wait to see him begin to walking out in the garden.

I’ll be sure to keep you updated.

How is your garden looking?  Is anything blooming yet?

January is off to a busy start.  We have gone from a house bursting at the seams to one that seems suddenly spacious after my two oldest daughters left for home with their children.  While I do miss them, I must admit that I never thought a house filled with 3 teenagers would seem quiet.

As I drove my oldest daughter and her family to the airport, I felt that familiar tickle in my throat and knew that I was getting sick.  I wasn’t too surprised with all of the busyness of the holidays that my resistance was low.  

A few days later, I was due to make an appearance on the television show, Arizona Midday, which airs on our local NBC television station.  The topic was to be about winter gardening tasks.

While I have been on television a few times before, this was my first time on this particular program.  

As with the other times, I made a trip to the nursery for plants and other things for the television spot since the producers like a lot of props to make things look more interesting.

I came away with a bare root rose (my favorite Mr. Lincoln red rose), leaf lettuce and kale, parsley and cool season annuals for color.  Other props included different types of frost protection including frost cloth, old towels, and sheets.

Unfortunately, as the date of my television appearance neared, my cold got worse and evolved into a full-blown sinus infection.

So on a brisk winter morning, loaded up with cold medicine and a pocket full of kleenex, I loaded up my plants and other props and headed to the TV station along with my mother who came with me to help me stage the table and provide moral support.  

We spent a delightful time waiting to be escorted to the studio in the green room with a pair of chili cooks who were talking about an upcoming chili cookoff.

Finally, it was time for the gardening segment, which went quite smoothly – I didn’t cough or sneeze once.  The host was kind, gracious and most importantly – laid back and relaxed.

After returning home, I got on my favorite pair of sweats and got back into bed.  I am determined to kick this cold!

I hope that your January is off to a great start!
