Embracing the Desert’s Winter Palette

One of the delightful aspects of life in the Southwest is the vibrant outdoor spaces, especially during the winter season.

A Break from Landscape Critiques

For those who have been following my blog, you know I often share photos of landscape issues I encounter. But this time, the captivating winter beauty had me so enthralled that I didn’t notice any garden mistakes.

Captivating Winter Wonders

Join me in savoring the beauty of winter in the desert and perhaps find inspiration for your own landscape!

beautiful shrubs from winter beauty landscape

The Stars of the Winter Desert Garden

Valentine Bush (Eremophila maculata ‘Valentine’)

Hands down, my favorite shrub, the vibrant red Valentine Bush adds a burst of color from January through April. Even when not in bloom, its foliage remains attractive.

Golden Barrel Cacti (Echinocactus grusonii)

These sunny yellow cacti are drought-tolerant, low-maintenance, and add a cheerful touch to the garden year-round.

Large Desert Spoon (Dasylirion wheeleri)

With its spiky texture and gray-blue hue, the large desert spoon creates a captivating contrast in the landscape.

This is a great pairing of plants that I plan on using in future designs.

feathery cassia , pink fairy duster and Bursage are making winter beauty landscape

Feathery Cassia (Senna artemisioides)

Bright yellow fragrant flowers of feathery cassia (Senna artemisioides) are famous for their winter color. Nothing else brightens a dreary winter’s day as much as the color yellow. The silvery foliage of this cassia adds great color contrast and give off a silvery glow on a breezy day.

Pink Fairy Duster (Calliandra eriophylla)

In the background, you see the pink blooms of pink fairy duster (Calliandra eriophylla). Their uniquely shaped blooms look like a feather duster and hummingbirds find them irresistible. 

Bursage (Ambrosia deltoidea)

This native groundcover provides color contrast and thrives with minimal water.

This combination was well done but planted too closely together.

Blue Bells (Eremophila hygrophana)

Against the backdrop of yellow-flowering feathery cassia, a pair of boulders are decorated with blue bells (Eremophila hygrophana). These shrubs have lovely gray foliage and produce purple/blue flowers all year long.  This is a newer plant introduction getting a lot of attention. 

A golden barrel cactus offers great contrast along with a pair of agave.

firecracker penstemon (Penstemon eatoni)

Here is one of my favorite landscapes in this particular community.  I like the combination of cacti, flowering shrubs, and perennials that create a pleasing landscape.

Firecracker Penstemon (Penstemon eatoni)

A trio of flowering firecracker penstemon (Penstemon eatoni) easily catches your eye. They are one of my favorite perennials in my own garden and flower January through April in the low desert.

In another landscape, firecracker penstemon is used as part of a wildflower planting, backed by desert spoon and purple trailing lantana.

Pink Muhly Grass (Muhlenbergia capillaris)

Ornamental grasses add great interest to the winter landscape and pink muhly (Muhlenbergia capillaris) is one of my favorites. Their burgundy plumes, which appear in fall fade to an attractive wheat color in winter. Soon, they will be pruned back to 3 inches in preparation for a new growth cycle.

Some beautiful winter landscapes

Blue Palo Verde Tree (Parkinsonia florida)

Some landscapes look attractive using a minimum amount of plants.  The key is to use a variety of different plants – not just shrubs or cacti.  In this one, a blue palo verde (Parkinsonia florida) overlooks a planting of purple trailing lantana (Lantana montevidensis) and desert spoon.  While the lantana is frost tender, the canopy of the tree provides it some protection from frost.

‘New Gold’ Lantana (Lantana ‘New Gold’)

It’s important to anchor the corners in your landscape – particularly those next to the driveway. Here is an example of how to combine plants that look great throughout the year. When warmer temps arrive  ‘New Gold’ lantana (Lantana ‘New Gold’), bursts forth with colorful blooms that last until the first frost. In winter, golden barrel cacti attract the attention and keep you from noticing the frost damaged lantana. 

little leaf (foothill) palo verde (Parkinsonia microphylla)

This street planting also attracted my attention with the row of little leaf (foothill) palo verde (Parkinsonia microphylla) trees, Valentine shrubs and purple trailing lantana. I should note that lantana doesn’t usually flower much in winter, but in mild winters, they do.

red-flowering chuparosa (Justicia californica)

Chuparosa (Justicia californica)

An almost leafless mesquite tree stands sentinel over a planting of red-flowering chuparosa (Justicia californica). This shrub has lovely green foliage and tubular flowers that drive hummingbirds crazy with delight.

Adding Cool-Season Beauties to Your Landscape

s you can see, the Southwestern landscape is filled with beauty and color, even in winter. Unfortunately, many homeowners tend to focus on plants that primarily bloom during the spring and summer months. While these choices can create stunning gardens during warmer seasons, they often leave gardens looking somewhat lackluster during the winter months.

Winter gardening in the Southwest offers a unique opportunity to infuse your landscape with captivating colors and textures, providing a visual treat even when the temperatures drop. By incorporating cool-season beauties like the vibrant Valentine Bush, cheery Golden Barrel Cacti, and the elegant Firecracker Penstemon, you can ensure that your garden remains a source of joy throughout the year.

Embracing winter-friendly plants doesn’t mean sacrificing the visual appeal of your landscape during the colder months. Instead, it allows you to celebrate the unique beauty that the winter season brings to the desert garden. So, why not take this opportunity to diversify your garden’s plant palette and create a lively and colorful outdoor space that shines year-round? By doing so, you can revel in the splendor of your Southwestern garden, no matter the season.

Spring Cleaning in the Garden: How to Prune Shrubs

Prune Shrubs, Globe Mallow (Sphaeralcea ambigua) before pruning

We had experienced a delightful spring with hot temperatures staying away for the most part. The weather has been so lovely that I’ve been spending a lot of time out in the garden. One garden task that has needed to get done is pruning back my winter/spring flowering shrubs.

What are winter/spring flowering shrubs you may ask? Well, they are those that flower primarily in late winter and on into spring. In the Southwest garden, they include cassia (Senna species), globe mallow (Sphaeralcea ambigua), and Valentine bush (Eremophila maculata). 

The time to do this varies depending on the plant and the region you live in, but generally, you want to prune them back once flowering has finished. 

I’ve decided to show you how I have pruned my cool-season shrubs and I find that using hedge trimmers make quick work of this job. Yes, I realize that I preach against using hedge trimmers for ‘poodling’ flowering shrubs into formal shapes, BUT they are very useful for corrective pruning for the health and beauty of your shrubs. I only use them ONCE a year.

Above, is a photo of my red globe mallow shrubs before I pruned them. They put on a beautiful show for several weeks, but have gone to seed, and they aren’t particularly attractive in this state.

This is what they look like after pruning. As you can see, they have been pruned back severely, which is needed to keep them attractive and stimulate attractive, new growth. Don’t worry, while they may look rather ugly, in a few weeks; they will be fully leafed out.

Here is one of my Valentine (Eremophila maculata ‘Valentine’) shrubs. This is one of my favorite plants, and it adds priceless winter color to my garden. One of the things that I love about it is that it needs pruning once a year when the flowers have begun to fade.

I prune mine back to approximately 2 feet tall and wide, but you could prune it back even further. This pruning is necessary to ensure a good amount of blooms for next year. Don’t prune it after this as you will decrease a number of flowers that will form later.

Finally, it was time to tackle pruning my feathery cassia shrubs (Senna artemisoides). I love the golden yellow flowers that appear in winter and last into early spring. They add a lovely fragrance to the garden as well. However, once flowering has finished, they produce seed pods that will turn brown and ugly if not pruned.

I’ve created a video to show you how to prune these shrubs. Unlike the others, I only prune them back by 1/2 their size.

*As you can see in the video, my grandson, Eric was having fun helping out in the garden.

That is all the pruning that these shrubs will receive, which will keep them both attractive and healthy.

It’s worth noting that hedge trimmers aren’t a bad tool to use – rather, the problem is when they are used incorrectly to prune flowering shrubs excessively throughout the year.

I hope that this post is helpful to you as you maintain your shrubs. If you’d like to learn more about pruning shrubs in the desert garden, I invite you to learn more about my popular online pruning workshop. I’ve helped countless people just like you learn how to maintain beautiful, flowering shrubs with pruning twice a year or less!

Feathery Foliage, Yellow Flowers and Tough as Nails

Last month, I asked you on my Facebook page, which plant I should profile in my upcoming article for Houzz.com  (Every month, I write a plant profile on plants that grow well in the Southwest.)  

My blogger friend, Becky, who lives in Tucson, mentioned that Feathery Cassia (Senna artemisoides) would be a good choice.

Surprisingly, I hadn’t thought to feature this great shrub considering that I have used it in landscape designs in the past.

Feathery Cassia (Senna artemisoides)

In 2012, I was asked to design the plantings along a street in Rio Verde, AZ.

In addition to succulents, trees, perennials and other shrubs – Feathery Cassia was one shrub that I wanted to be sure to include due to its low-maintenance, drought-tolerance and gorgeous winter color.

Valentine (Eremophila maculata 'Valentine')

In just over a year, Feathery Cassia has a good start, but will grow much larger.

I love pairing this shrub with Valentine (Eremophila maculata ‘Valentine’) with its red flowers.

Feathery Cassia (Senna artemisoides)

I like this shrub so much, that I have planted 5 of them along in my own garden, along a long block wall.  I can’t wait until they start growing.
