Has this happened to you?  You walk through the nursery, and you spot “the perfect plant.”   You can envision it in your yard and know precisely where you will put it.  

After coming home and planting it, you pat yourself on the back for finding such a great plant.  Time passes, and your beautiful plant starts to grow, and grow and grow.

Fast forward a year or two now it looks bad unless you constantly prune making it high maintenance.  Now your beautiful plant no longer looks so lovely (above and below).  It now looks more like a ‘cupcake’ because you have had to prune it back to keep it small enough for your space.  

No more flowers, no nice foliage…

 More ‘cupcakes.’

Unfortunately, there is an epidemic in our area of homeowners and landscapers who prune flowering shrubs so that they end up looking like ‘cupcakes’ or ‘poodles’ just so that they fit into their allotted space.  More about that in another post…

Also with flowers this beautiful, why plant it somewhere where you will have to prune them off so that it can fit?  

So our lesson is…. be sure to READ THE LABEL of plants before you buy them, which should list how large they will grow, along with the correct sun exposure.  If it’s not listed, ask the nursery salesperson for this information, or use your smartphone to get the information.  

Then you can go home and place your new “perfect plant” where they will have plenty of room to ‘stretch out’ and dazzle you with their beauty. 

**Allowing enough room for plants is just part of what it takes to grow attractive shrubs.  Pruning is the next part of the equation.  Click here for guidelines on how to properly prune your flowering shrubs.

Baja fairy duster shrubs up close

Baja Fairy Duster is Hummingbird Food in the Native Garden

Baja fairy duster (Calliandra californica) is a must-have for the desert garden.  There is so much to love about this shrub.  

My favorite attribute is that it flowers off and on all year.  Its red flowers are shaped like miniature feather dusters.  Also, this plant attracts hummingbirds, is low-maintenance, drought tolerant and great by swimming pools because of its low litter.

Baja fairy duster has a vibrant red flower, which is often a color missing in the desert plant palette.  The majority of flowering occurs spring through fall, but some flowering can occur in areas that experience mild winters.  

It is native to Baja California, Mexico and is also called red fairy duster by some.  It is evergreen to 20 degrees F.  During some unusually cold winters when temperatures dropped into the high teens, I have had some killed to the ground, but they quickly grew back from their roots. 

Baja fairy duster flowers

Landscape Uses for the Red Blooming Shrub

This shrub grows to approximately 4 – 5 ft. High and wide, depending on how much you prune it, so allow plenty of room for it to develop.  

It makes a lovely screening shrub, either in front of a wall or blocking pool equipment, etc.  It also serves as a colorful background shrub for smaller perennials such as damianita, blackfoot daisy, Parry’s penstemon, gold or purple lantana and desert marigold.  

Baja fairy duster can take full sun and reflected heat but can also grow in light shade.  It is not particular about soil as long as it is well-drained.

Baja Fairy Duster Maintenance

As I mentioned before, this is a very low-maintenance shrub.  Some people shear this shrub, which I DO NOT recommend.  This removes most of the flowers and takes away from the natural shape of this shrub.  However, it’s size can be controlled with proper pruning.  Pruning should be done in late spring and should be performed with hand-pruners, NOT hedge clippers.

Baja fairy duster does require regular irrigation until established but then is relatively drought-tolerant.  However, proper watering is needed for it to look its best and flower regularly, which is what I do.  

Other than adding compost to the planting hole, no other amendments or fertilizer is needed.  Most native desert plants have been adapted to growing in our nutrient deficient soils and do best when left alone in terms of fertilizing.  I tell my clients to fertilize only if the plant shows symptoms of a nutrient deficiency.

So, go to your local plant nursery and get some of these beautiful shrubs for your garden.  Then, while you sit and enjoy its beauty, you can debate what you love most about it….the beautiful year-round flowers, the hummingbirds it attracts, it’s low-maintenance, or come up with your reasons.

Discover Stunning Plant Combinations

Do you ever wonder what plants look good together?  Below are pictures of some of my favorite plant combinations along with some general guidelines that I follow when designing a garden. Keep in mind that planting similar plants together which require similar water needs makes it easier to maintain a landscape.

Color Harmony in Plant Combinations

Sometimes red and pink colors always complement each other. Introducing yellow flowering plants provide a high color contrast that brings out the red and pink colors.  Above is a golf course landscape that I planted with Valentine shrub (Eremophila ‘Valentine’), Parry’s penstemon (Penstemon parryi) and desert marigold (Baileya multiradiata) against the backdrop of foothill palo verde trees.

plant combinations

 Parry’s agave (Agave parryi) with purple trailing lantana (Lantana montevidensis)

Succulent and Perennial Pairings

Also, succulents paired with perennials almost always complement each other with their contrasting shades of green and textures.  Other recommended succulent and perennial pairings include desert spoon (Dasylirion wheeleri) alongside black dalea (Dalea frutescens), prickly pear species with penstemon or try octopus agave (Agave vilmoriniana) with purple or white trailing lantana.

 Autumn Sage (Salvia greggii ‘Red’)

Emphasizing Colors with a White Flower Contrast

 Blackfoot Daisy (Melampodium leucanthum)

I use plants with white flowers as a backdrop for plants with red, pink and purple flowers; I like the way the white flowers emphasize the other colors.

Using the Color Wheel for Plant Combinations

plant combinations

 ‘Rio Bravo’ Sage (Leucophyllum langmaniae) & Red Bird-of-Paradise (Caesalpinia pulcherrima)

Most of the time the pairing of purple flowering plants with those that have orange flowers always looks great.  When deciding what colors look good when paired together, it helps to look at a color wheel. In general, the colors that are opposite each other look great when paired together because their colors contrast so well. Other orange, purple plant combinations to try are cape honeysuckle (Tecomaria capensis) with (Leucophyllum species), or Mexican honeysuckle (Justicia spicigera) with purple lantana. 

The Power of Yellow Flowering Plants

plant combinations

 Angelita daisy (Tetraneuris acaulis) and parry’s penstemon (Penstemon parryi)

Also, I believe that any garden looks better with some yellow flowering plants.  As I mentioned earlier, the color yellow makes the other plants look better, (think of the color wheel).   I have had clients that have said they do not like yellow until I show them how much better their other plants look when we introduce just a few yellow flowering plants to their landscape and they quickly change their mind.

Yellow Bells

Large Shrub Plant Combinations

Bougainvillea 'Barbara Karst'

 Bougainvillea ‘Barbara Karst’

I often recommend the following for those who are looking for large shrub combinations. Okay, I realize that many people either love or hate bougainvillea. Personally, I love them.  I have two bougainvillea and since I don’t have a swimming pool, so I am not bothered by their litter. Their beautiful and vibrant colors are amazing.

Timing Matters in Plant Pairings

I pair my bougainvillea with yellow bell shrubs.  Their colors contrast nicely, and they screen out the back wall of my garden. I give them plenty of room to grow, and they produce beautiful flowers spring through fall. If you do have a swimming pool and don’t like bougainvillea, how about trying orange jubilee (Tecoma hybrid ‘Orange Jubilee’) and Texas Sage (Leucophyllum frutescens) together?

Weber's agave

 Weber’s agave (Agave weberi) and purple trailing lantana

I have just one more tip – if you want to pair flowering plants together to enjoy the contrasting colors, make sure that they bloom at the same time of year. It is so easy to visit the plant nursery and see the pretty photos of flowers on the different plants and pick what ones you think will look great together only to discover later that one flower in the fall while the other blooms in spring and so you never see their flowers at the same time.

So, visit your local nursery and try some of the suggested plant combinations or see what beautiful plant pairings you come up with for your garden.

The time has finally arrived!  Summer temperatures are but a memory and fall is here! 

Every year we wait for the end of summer so we can start adding plants in the garden. The only question is what plants will I add?

The possibilities are endless…    

add new plants

 Purple Lilac Vine (Hardenbergia violaceae)

The signs that fall in the desert may not be as evident as in other parts of the county, yet they are here.  Elongating shadows, cooler evening temperatures along with increased plant growth and flowering are clear signs that the heat of summer is fading and cooler temperatures are on their way.

add new plants

 Blackfoot Daisy  (Melampodium leucanthum)

October and November are the best months in which to plant most types of plants in the desert.  The reason for this is that plants use the cooler weather in which to grow a healthy root system so that by the time that the summer arrives, they are ready to handle the stress of the intense heat.

add new plants

 Parry’s Penstemon  (Penstemon parryi)

Most trees, shrubs, perennials, and succulents can be planted now.  Stay away from planting palms, bougainvillea, lantana and other plants that suffer frost damage during the winter months.  They do best when planted in the spring.

add new plants

 Chaparral Sage   (Salvia clevelandii)

As in all climates, be sure to plant correctly.  Dig a hole three times as wide as the root ball but no more profound than the root ball.  This will allow the roots to grow outwards more quickly.  

When growing native plants, you do not need to add any amendments to the hole as this can cause the roots to just stay in place, enjoying the nutrient-rich soil, instead of venturing out into the regular soil.  If you do decide to add amendments to the soil, be sure to incorporate them well with the existing soil.   

Newly installed plants will initially require more water than established plants, so be sure to adjust your watering schedule accordingly.

Fall Planting: How to Select Plants

drought tolerant

Globe mallow (Sphaeralcea ambigua) brings a unique “cottage-garden” feel to the desert plant palette along with some surprises. In spring a flush of beautiful flowers are produced that will cause people to stop in their tracks. After that, globe mallow will bloom off and on throughout the summer and fall.  

This shrubby, perennial is native to the Southwestern areas of North America where it is found growing along washes and rocky slopes. They grow quickly and reach approximately 3 ft. X 3 ft. in size. Globe mallow is cold hardy to about 20 degrees F.

Although most globe mallow plants produce orange flowers, they are available in other colors including pink, purple, white, red and shades in between. At the nursery, you will usually see the orange flowered variety available. However, some growers are beginning to stock selections of globe mallow in different colors. But buyer beware; unless specially marked or blooming, you don’t know exactly what color flower you will end up with make sure if you want a certain color to check for mark.  

Often, the surprise occurs after you plant them and wait to see what color the flowers will be. I bought four globe mallow, out of bloom, for my garden and ended up with one red, two pink and one white. For those who do not like surprises in the garden, you can wait and buy them in bloom in the spring.

drought tolerant

USES: Globe mallow attracts hummingbirds as well as butterflies. They serve as a colorful backdrop for small perennials or small cacti. Consider planting with any of the following plants for a colorful desert flower garden – penstemon, desert marigold, ruellia, and blackfoot daisy. This beautiful but tough plant does best in full sun and performs well in areas with hot, reflected heat. Do not plant in shady areas as this will cause them to grow leggy.

Globe mallow do self-seed, and the seedlings can be moved and transplanted in the fall if desired. They are used frequently for re-vegetation purposes because they grow readily from seed.

Globe Mallow

MAINTENANCE: This pretty perennial is very low-maintenance.  No fertilizer or amendments to the soil are required. Prune once a year to approximately 6 inches to 1 ft. after it has finished blooming in late spring/early summer, which will help to prevent them from self-seeding, maximize future blooming and minimize unproductive, woody growth. Globe mallow is not the type of plant to repeatedly shear into a formal shape. When pruning, wear gloves and long sleeves since the tiny hairs on the leaves can be irritating to some as well as an eye irritant.

Once established, globe mallow is quite drought-tolerant, but will require supplemental irrigation for the best appearance and flowering. My globe mallow plants are connected to my drip-irrigation system and do very well when watered three to four times a month, spring through fall.

Globe Mallow

ADDITIONAL FACTS: Historically, globe mallow were used by Native Americans for medicinal purposes such as treating diarrhea, sore throats, eye diseases as well as skin disorders. Their roots were used for upset stomachs and poultices were made for treating swollen joints and broken bones.

Fall is Here! Time to Start Planting!

santa rita purple prickly cactus

Exploring the Beauty of Prickly Cactus

Do you like prickly cactus? I have a few favorites, one being the Santa-Rita Prickly Pear (Opuntia violaceae var. santa rita). The color contrast of their blue-grey pads and the shades of purple are so striking in the landscape.

The Santa-Rita Prickly Pear: A Stunning Accent Plant

The Santa-Rita prickly pear is a captivating addition to any landscape. Its blue-grey pads and vibrant shades of purple create a visually striking contrast. Not only is this cactus aesthetically pleasing, but both its pads and fruit are edible (though you may want to remove the spines first). Cold temperatures and drought conditions intensify the vivid purple color of this remarkable cactus.

Native Plant Beauty of the Southwest

Native to the Southwestern regions of North America, the Santa-Rita prickly pear can reach impressive dimensions, growing as large as 6 feet by 6 feet. However, if you prefer a smaller size, careful pruning at the junction where the pads connect can maintain a more manageable shape.

Blossoms and Wildlife with Prickly Cactus

In spring, the Santa-Rita prickly pear graces the landscape with lovely yellow flowers that later give way to red fruit during the summer months. Keep in mind that javelina, rabbits, and pack rats are occasional visitors that might nibble on the pads, while pack rats ingeniously use the pads to build their homes.

Handle with Care: Dealing with Spines and Glochids

Prickly pear pads are covered with clusters of 2″ spines and tiny spines known as glochids. Glochids are especially irritating to the skin and easily detach from the pad, making them challenging to remove. When handling these prickly cacti, use multiple layers of newspaper or a piece of carpet to protect your hands. Avoid gloves, as glochids can render them useless.

Removing Glochids Caused by Prickly Cactus

If you encounter glochids with prickly cactus, there are different methods to remove them, including applying Elmer’s glue, allowing it to dry, and then peeling off the glochids. However, many find greater success using duct tape for a more efficient removal process.

Versatile Uses in Landscaping

Beyond being a landscape accent, the Santa-Rita prickly pear serves as an excellent screen. Surprisingly, it can thrive in containers as well, although it’s essential to keep them away from high-traffic areas. These resilient cacti flourish in full sun or light shade and well-drained soil.

Low-Maintenance Prickly Cactus Beauty

Santa-Rita prickly pears are incredibly low-maintenance plants. When pruning, use tongs or newspaper to handle the trimmed pads. While they are highly drought-tolerant, occasional watering during the hot summer months, especially in the absence of rain, can enhance their appearance. Shriveled pads signal acute drought stress, so a little extra water can work wonders.

santa rita prickly cactus disease

Addressing the Cottony Mystery on Prickly Cactus

Some might mistake white, cotton-like areas on the pads as a fungal infection, but it’s actually caused by a small insect known as cochineal scale. Removing this cottony mass is simple—just spray it off with a strong jet of water from the hose.

pad cactus purchased at garden center

Propagation: A Simple Guide

You can propagate Santa-Rita prickly pear cacti with ease. Simply cut off a pad that is at least 6 inches tall, let it callus upright in a shady, dry spot for about two weeks, and then plant it with the cut end down.

Plant with the cut end down, do not water for the first month because the bottom is susceptible to fungal infections. After the first month, water every 2 – 3 weeks until established. 

Timing Matters

Planting in the summer requires shade until the cactus is established (approximately three months). However, it’s often advisable to wait until spring when the soil warms up for planting, especially in regions with cold winters.

Renewed Growth: Pruning and Propagation

For those with established Santa-Rita prickly pear cacti, you can rejuvenate growth by pruning or starting anew. Simply remove the cactus, cut off some pads, and replant them in the same location. Many have embraced this method and have been delighted with the results.

An Interesting Historical Fact

The Aztecs would cultivate prickly pear cactus infected with cochineal scale because the insects secrete a dark red dye with crushed. This was used to dye cloth. The Spanish exported this dye from Mexico back to Europe where it was used to dye royal garments and British military uniforms. The dye was highly valued by the Spanish, next to gold and silver. It takes 70,000 insects to produce 1 pound of dye.

summer is beginning

There are some signs that summer is beginning to fade and that fall is around the corner.  The stress that the high temperatures of summer bring has caused many plants to slow down their growth.  

However, the slightly lower temperatures in September bring on a flush of new growth for many trees, shrubs, and succulents in the garden.  I enjoy being out in my garden this time of year and seeing many of my plants rejuvenated.

With the somewhat cooler temperatures, I am now seeing many gardeners venturing outside and taking stock of the condition of their landscape.  Fall is a busy time in the desert garden because it is the ideal time to install many types of plants, which will be discussed in a separate post in early October.

summer is beginning

SHRUBS: I just finished lightly pruning my ‘Rio Bravo’ sage (Leucophyllum langmaniae).  Summer flowering shrubs that are cold-hardy look their best when lightly pruned at this time to help reign in rangy, sprawling growth. This should be only done with hand pruners only.  Do not use a hedge trimmer and shear your shrubs.  They should have a pleasing natural shape when you are finished.  Do not prune back frost-sensitive plants at this time.

summer is beginning

ANNUALS:  Although the local nurseries are abundant with winter annuals, I don’t recommend planting them now.  The temperatures are still quite hot, and there is a good chance that they will not make it.  

In the past when mid-September came, I would load up the truck with 100+ flats of annuals to plant around the community where I worked as the horticulturist.   I would then spent the next four weeks making repeated trips to the nursery to replace dead plants that just could not handle the heat of early fall.  From then on I would wait until October to change out summer annuals and replace with winter annuals.  As a result, we suffered very little plant loss.

summer is beginning

TREES:  Mesquite and Palo Verde trees that are overgrown can be lightly easily pruned back.  Resist the temptation to heavily prune at this time.  January and February is the time for heavy pruning to occur for these trees.

summer is beginning

SUCCULENTS:  Cacti, agaves and other succulent plants do best when planted when soil temperatures are warm, which makes September a great time to install them before cooler temperatures arrive.   Prickly Pear cactus can be pruned back this month if needed.  Problems with agave may show up this time of year. 

summer is beginning

If your agave suddenly collapses, there is a good chance that they have gotten an infection with agave snout weevil.  There is no cure and the agave should be removed, it will be smelly due to the decay the weevil causes – and not just a little stinky.

One of my (least) favorite memories happened years ago when I worked as a horticulturist on a golf course.  One year, we had to remove countless agaves throughout the landscapes due to a large infestation – the smell was awful.  If this happens to your agave, do not plant another agave in the area – use another type of plant instead.

Roses

ROSES:  Roses should be lightly pruned and fertilized this month (see earlier post for details).

citrus trees

CITRUS:  Make sure to fertilize your citrus trees if you have not already done so (see earlier post for details).

Large blooming palo verde an Iconic tree

  Iconic tree, Blue Palo Verde (Parkinsonia florida)

When people think of the Sonoran desert, hillsides studded with saguaro cactus and cholla often come to mind.   But interspersed between the cactus, you will find the palo verde, an iconic tree with their beautiful green trunks and branches.

An Iconic Desert Tree; The Palo Verde

The word “Palo Verde” means “green stick” in Spanish, referring to their green trunk, which is a survival mechanism in response to drought.  

Palo verde trees are “drought deciduous,” which means that they will drop their leaves in response to a drought situation.  Their green trunks and branches can carry on photosynthesis, even in the absence of leaves.

Palo Verde Trees Are Nurse Plants to Saguaro Cacti

Palo verde trees act as a “nurse plant” to young saguaro cacti by protecting them from the cold in the winter and from the intense sun in the summer.  Beautiful, yellow flowers are the product in the spring.    

Desert Museum Palo Verde Flower

There Are Several Species of Palo Verde

There are three species of palo verde that are native to the desert Southwest; blue palo verde (Parkinsonia florida), formerly (Cercidium floridum), foothill palo verde (Parkinsonia microphylla), formerly (Cercidium microphyllum) and ‘desert museum’ palo verde (Parkinsonia x ‘Desert Museum’).

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

Another species of palo verde that is prevalent in the landscape are called palo brea (Parkinsonia praecox), formerly (Cercidium praecox).  They have a dusty green trunk and branches that twist and turn.  Their cold hardiness range is around 15 to 20 degrees F.

Palo verde Iconic tree

 Iconic tree, Palo Brea

Palo Verde Landscape Uses

Palo verde trees serve as beautiful specimen trees where their green trunks, branch structure, and flowers serve as an attractive focal point in the landscape.  They are drought tolerant, once established and provide lovely filtered shade year-round.  

When deciding where to place your tree, be sure to take into account that they need a lot of room to grow, mature sizes are listed below.  

Palo Verdes don’t do well when planted in grass and will decline over time.  Locate away from swimming pools due to flower litter in the spring.

Because of their more massive thorns and branching tendency to point downwards, palo brea trees aren’t recommended in areas close to foot traffic.  

Mature Sizes:

  • Blue Palo Verde – 30 ft x 30 ft
  • ‘Desert Museum’ Palo Verde – 30 ft high x 40 ft wide
  • Palo Brea – 30 ft x 25 ft
  • Foothills Palo Verde – 20 ft x 20 ft

As with many desert trees, Palo Verde trees have thorns, except for the ‘Desert Museum’ Palo Verde.

Basic Palo Verde Maintenance

Pruning for Canopy Elevation and Structural Integrity:

Pruning Palo Verde trees in your desert Southwest garden is a crucial aspect of maintaining their health, aesthetics, and structural integrity. One of the primary objectives of pruning is to elevate the canopy, ensuring it remains well-balanced and visually appealing. This practice involves selectively trimming the lower branches to create a more elevated and open canopy. By doing so, you allow for better air circulation and light penetration, which can promote overall tree health and reduce the risk of disease.

Steering Clear of Hedging and Topping:

While pruning is essential, it’s equally vital to understand what not to do. Avoid two harmful practices: hedging and topping.

  1. Hedging: Hedging involves indiscriminate shearing or cutting of branches to create a uniform, artificial shape. This practice is highly discouraged for Palo Verde trees, as it not only compromises the tree’s natural beauty but also disrupts its growth patterns. Hedging can lead to dense, bushy growth with weaker, more susceptible branches.
  2. Topping: Topping is the severe cutting of the uppermost branches, often leaving stubs or bare trunks. This practice is detrimental to the tree’s health and stability. When Palo Verde trees are topped, they respond with a vigorous burst of new growth that tends to be weak and prone to breakage. Topped trees are also more susceptible to pests and diseases.

The Proper Tree Pruning Approach:

Instead, adopt a thoughtful and strategic approach to pruning your Palo Verde trees. Start by identifying dead, diseased, or damaged branches, and promptly remove them. This eliminates potential entry points for pests and diseases, promoting tree health.

Next, focus on elevating the canopy by selectively pruning lower branches. When selecting branches for removal, prioritize those with narrow crotches or those that cross and rub against each other, as these can weaken the overall structure.

Consider hiring a certified arborist or a professional tree service to ensure that your Palo Verde trees receive the care they deserve. These experts have the knowledge and experience to prune your trees correctly, preserving their natural form and promoting robust, healthy growth.

By following proper pruning practices and avoiding hedging and topping, you can help your Palo Verde trees thrive in your desert Southwest garden. A well-maintained Palo Verde tree not only adds to the beauty of your landscape but also provides valuable shade and habitat for local wildlife while remaining resilient in the harsh desert environment.

Palo Verde is My Favorite Tree

As a landscape manager, horticulturist and arborist, I have grown and maintained all of the palo verde species mentioned, and I truly enjoy them all.  However, at home, I have 4 ‘Desert Museum’ trees. 

In comparison to the other species, their trunks are a deeper green; they produce larger flowers, are thornless and grow very quickly in the desert.  Also, they require little, if any, tree staking when planted. Simple amazing!

Blooming Flowers

The blooming of my desert willow tree (Chilopsis linearis), is beginning to slow down.  The leaves will fall in December.  However, there were a few lovely pink flowers left.

Also, the recent monsoon storms have caused my ‘Rio Bravo’ sage, (Leucophyllum langmaniae), to burst out in flower.

The vibrant colors of my red bird-of-paradise, (Caesalpinia pulcherrima) add vibrant color to my garden and nectar for hummingbirds.  

In another month, many of these flowers will no longer be flowering, but until then, I’ll enjoy the view.

Yellow Bells

This beautiful plant is one of my favorite shrubs in the garden – so much so, that I have three.  Yellow bells produce bell-shaped flowers beginning in spring and lasting through the fall months until the first frost.

 Hummingbirds and butterflies are attracted to the flowers.  The vibrant green foliage and colorful flowers make this shrub a welcome addition to any desert landscape. 

Yellow Bells is a large shrub that grows to a height of 4 – 8 ft. and spreads 3 – 8 ft. wide.  You can find its native habitat in the Americas.  There are two different types; Tecoma stans angustata and Tecoma stans stans.  Visually, the most significant difference is in the shape of the leaves.  Tecoma stans stans had a broader leaf and are pictured above and below.

Yellow Bells

USES:

Because of its size, this large shrub makes a great backdrop plant.  I have used it to screen fences, sheds and also planted it up against the house.  Yellow Bells works well as a tall, naturally-shaped hedge.  This shrub thrives in full sun to filtered shade.  They do best in warm-winter areas but can be successful as a summer annual in colder regions.

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

MAINTENANCE:

This shrub is relatively low-maintenance.  It will freeze back in the winter months when temperatures go below 28 degrees F.  Since it blooms on current season’s growth, all that is required is to prune back the frost damage in early spring.  Seed pods are produced and can be removed if desired, which will extend the bloom period and improve the appearance, (the seed pods do not bother me, and I do not remove mine).   After an initial application of slow-release fertilizer when planting Yellow Bells, I have not needed to fertilize further. 

**Occasionally, caterpillars will appear but can be easily removed by spraying some BT (Bacillus thuringiensis) which is an organic pesticide.

Yellow Bells

COMMON NAMES: 

There are many familiar names for these beautiful shrubs.  Tecoma stans angustata is native to the Southwestern US and northern Mexico and goes by the names Arizona yellow bells, yellow bells, and yellow trumpet bush. 

Tecoma stans stans are native to Florida, the Caribbean and parts of South America and also goes by the name of yellow bells and sometimes yellow elder.  Because of the overlap of familiar names, be sure to purchase plants based on their scientific name.
