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.

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

‘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

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 (Tecoma stans stans)

Large Shrub Plant Combinations

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 (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.

Fall is Here! Time to Start Planting!

Arizona garden, California desert garden, desert gardening, Las Vegas gardening, Southwest 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…

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.

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.

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.

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.

Bower Vine (Pandorea jasminoides)

So visit your local nursery and get planting!

Fall Planting: How to Select Plants

Drought Tolerant and Beautiful: Globe Mallow

Arizona garden, California desert garden, desert gardening, Drought Tolerant, Las Vegas gardening, New Mexico garden, Southwest garden

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.

Drought tolerant

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.

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.

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.

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.

Purple, Prickly and Beautiful: Santa-rita Prickly Pear

Arizona garden, Cactus/Succulents, desert gardening, Southwest garden, Succulent Gardening

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.

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.

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.

*This is but one of many beautiful prickly pear species available to the home gardener. Do you have a favorite species of prickly pear cactus?

Drought Tolerant, Year Round Bloom: Angelita Daisy

desert gardening, Drought Tolerant, Fuss Free Plant, Perennial, Southwest garden

Angelita Daisy (Tetraneuris acaulis) syn. Hymenoxys acaulis

Angelita daisy is a beautiful, small perennial that is a reliable producer of yellow daisy-like flowers throughout the year. The heaviest blooms occur in winter and spring, which makes this little plant an asset to the landscape. They grow to approximately 10″ high and up to 18″ wide.

Plant angelita daisy in full sun for best appearance and in well-drained soils. However, with our hotter summers, avoid placing them in areas that receive reflected heat, such as against a wall or near driveways, sidewalks, or the street.

Periodic pruning of the flowers helps to promote additional flowering. No supplemental fertilizer is needed.

I have used angelita daisy many times in landscapes that I have managed, and they are very low-maintenance. They are among my top ten favorite plants and I use them often when designing new landscape areas. Angelita looks best when planted in groups of 3 – 5. Their yellow color accent purple and red flowering plants. They especially look nice when planted next to boulders in the landscape.
