FREEZE WARNING - Cover your plants

There is a deep freeze warning here in the Phoenix valley tonight through the next few nights. You need to cover your plants. You can wrap the trunk of your palm trees and other trees, cover the canopy if possible, especially Ficus trees. Drape all of your plants and put cups on your cactus. Many of our desert friendly plants will die in a hard freeze like this.

Desert garden worth the effort

Here is a great article from Kath Babcock from the Desert Botanical Garden. She talks about Arizona gardening and how it differs from the midwest gardening. In Arizona we have two seasons for vegetable gardening: Fall and Spring. In other parts of the country everything is planted in for the summer garden. We are not able to plant everything we need for a salad at one time because different plants are planted at different time, depending on their heat tolerance. She also talks about our drip irrigation systems. Due to the little amount of rain we get here in the Arizona desert, everything is on a drip system to meet the watering needs of the plants. For help with your Arizona Desert Garden call a local licensed landscape contractor. Arizona Living Landscape & Design 480-390-4477. If you would like help installing, designing or repairing your irrigation system, we can also help you.

Eremophila Maculata Valentine Bush

Eremophila Maculata Valentine or Emu Bush.

This is an evergreen shrub with lush, green foliage. It will gro to 4' high by 5' wide and produces red tubular flowers from winter to early spring. The leaves are tinged red in winter. This is an excellent choice for gardens needing some winter color. It has showy red-rose blooms that cover the foliage, is hardy to 15 degrees, and is extremely drought tolerant and does well in full sun.
Plant in well drained soil and allow to dry out between waterings. Shear after blooming, usually in March to encourage bushiness. Plant in a space that needs winter color. It will be a striking contrast to other desert plants.

Arizona salt tolerant plants for the desert

Chinese Pistache (Pistacia chinensis). This is an ornamental deciduous tree with bright green leaves that turn red in the fall. The female plant produces clusters of pepper seeds. It grows up to 40' high and 30' wide. The most interesting aspect of this tree it that it turns a brilliant redish/orange in fall. Ths is the only desert tree whose leaves turn this shade of red. This tree is hardy to below 20 degrees and is heat and drought tolerant, requires little maintenance, and is resistant to oak root fungus. Plant this tree in well draining soil, water deeply and infrequently.

Flowers for Winter Color in Arizona Low Desert

This is the season for flowers in Arizona. Time to plant and enjoy the winter blooms. Below is a short list of my favorites. For a more complete list check out this website: University of Arizona

Calendula or Marigold: They come in orange or yellow colors, can take full sun, easy to grow, get 15-18" high so would be used as a focal point in the center of a bed or in the back, take minimal water, edible, make a good cut flower, attracts butterflies and reseeds. This plant can be planted Sep. through Nov. and will bloom Dec. through May in the Arizona low desert elevations.

Geranium: They come in red, purple, pink, orange, yellow, or white. Geraniums get 12-18" tall, take partial sun, lots of water, and are easy to grow. They can be planted in the Arizona low desert from Sept. through April and will bloom into June.


Pansies: They come in blue, purple, orange, yellow, white, red, and pink. Pansies get 6-12" tall, can be planted in sun to partial sun but will do better when the heat hits in partial sun, have average water needs, are edible, and are easy to grow. Pansies can be planted Oct. through Feb. in the Arizona low Desert and will bloom through April/May depending on weather.


Petunia: They come in blue, purple, yellow, pink and white. Petunias grow 6-18" tall, require a lot of water, are easy to grow, attract butterflies, and are fragrant. They can be planted Sept. through March and will bloom Oct., Nov., March, April, and part of May. They are frost sensitive and will die off with frost and need to be replanted. May survive light frost if covered.


Snapdragon: They come in purple, red, pink, yellow, and white. Snapdragon will grow 6-36" tall. These are the long stalk type flowers you see in the center or back of arrangements. They do best in full sun, average water, easy to grow and make a good cut flower. Snapdragons can be planted Oct. through Feb. and will bloom from Nov. into May.


Sweet Alyssum: These come in white, blue, pink, or easter bonnet. They are low growing and make a very nice border flower. They do well in full sun to partial shade, take quite a bit of water, are easy to grow and have a nice fragrance. They can be planted Oct. through March and will bloom Oct. through May.


For best results and an abundance of foliage and blooms use lots of mulch and a good pre-plant fertilizer like 16-20-0 ammonium phosphate. Water only enough to keep the soil slightly moist or slightly dry. Too much water causes fungi and will kill the plants just as quickly as not enough water. Also remember if the weather calls for a heavy frost or even a light one cover the flowers with a sheet all the way to the ground. This will help to ensure they stay alive and bloom all winter.

Christmas Cactus Bloom Preparation

Time to think about your Christmas Cactus Blooms. Christmas Cacti (Schlumbergera russelliana) will start setting buds to flower in time for the holidays. Apply a phosphorus fertilizer in September to promote the bud development and water well. Each evening place the plant in total darkness for 12-14 hours until early October, if possible. Move the plant in bright light but not direct sun during the day. Water when the top inch of soil dries out. It may take 4-8 weeks to bud.

Arizona Desert Summer Flowers

It is difficult to plant flowers with lots of color that will actually survive in the extreme Arizona summer heat. Below are a few that tend to fare well and will work in containers.

Vinca - a summer favorite. These will do well in full sun to partial shade. They need water daily in extreme temperatures and will bloom from spring until frost.






Celosia - this is a flower that I don't have much experience with but plan to plant it this summer. This flower is very hardy and likes the sun. They come in different varieties such as the New Look or China Town.




Portulaca - this is fast growing ground cover type of plant. They love the sun and blooms all over the plant.

Poolside Plants for the Arizona Desert

Here are some perfect pool friendly plants that will flourish in the Arizona summer Heat.


Foxtail Agave - (Agave attenuata)
This is a slow-growing ornamental succulent with bluish-green leaves. It will produce a pale-yellow flower after it reaches 10 years of age and will die after it blooms. The Foxtail Agave will generate offshoots from
the mother that can be transplanted in the yard. This plant will make a bold statement in your landscape and it offers tropical appeal. Agave's do well in our soil and the Foxtail Agave does not have any sharp spines.

The Foxtail Agave does better in light shade to part sun with regular watering in the summer. It will need frost protection in the winter below 30°. It is perfect for containers, borders, rock gardens, or planted in groups.



Twisted Leaf Yucca (Yucca rupicola)
The Twisted Leaf Yucca us a small trunkless plant with olive-green leaves that twist as they age. It produces spikes of creamy white flowers in summer that can grow up to 5 feet tall. The main rosette can reach 2 feet high by 3 feet wide and dies after blooming. It produces several offsets that will regrow. The Twisted Leaf Yucca has eye-catching blooms, has low-water use and is very heat tolerant. It is hardy to -10°. This plant does well in full sun to partial shade in well-draining soil.

Yellow Yucca - (Hesperaloe parviflora ‘Yellow’)
The Yellow Yucca is a clumping perennial that grows to 3 feet tall and wide. Creamy yellow flowers appear late spring through fall on spikes that reach 6 feet high. The blooms are long-lived, the plant is drought-tolerant, cold hardy to -20°; handles reflected heat.
The Yellow Yucca can be planted in full sun. It is tolerant of most soils but must have good drainage. Extra summer watering helps plant develop faster. Remove flower stalks after blooming. It is striking when grown in masses or alongside red-flowering flora. Perfect for xeriscape and cactus gardens. Once established, it requires little or no irrigation. All in all, yellow yucca is one of the toughest and most maintenance-free plants.
