Rocky Point Ice Plant If you're having a hard time giving up the notion of a
green lawn, Rocky Point ice plant may win you over. Its succulent, bright green
leaves provide a lush backdrop for the yellow daisy-like flowers. This ground
cover blooms off and on nearly all year, with short breaks in the winter and
summer. Rocky Point ice plant grows to about 10-12 inches tall by 3-4 feet wide.
In very hot summers it can burn back, but re-grows quickly as soon as the
weather cools off in the fall. I've been told that birds favor the succulent
leaves, pecking them to extract liquids in the hot summer months. Malephora
lutea is hardy to the 15° F. USDA Zone 8.

Often known as the Barbados Cherry or Acerola, this mounding shrub from southern Texas to the West Indies is an underused ornamental. The compact selection George Hull has developed came from Mary Irish's garden and we offer cultivar name 'Little Mary' in her honor. This selection has short internodes and a compact growth habit to 3, maybe 4'. It has small wavy leaves, which make it ideal as a compact, informal hedge-type shrub. In addition, from early summer to fall it is covered with small light pink flowers that faintly resemble those of a crape myrtle. Each 5 petaled flower is about 1/2 inch across and is followed by bright red, cherry-like fruit. It is not uncommon to have both flowers and fruit appear at the same time. Typically the tart but edible fruit is one-half to one inch in diameter, but our selection has much smaller fruit. The flavor has been described as sweetly acidic with a slight hint of apple. Barbados cherry may be collected for preserves or eaten from hand. High in ascorbic acid the species was once cultivated as a natural source of vitamin C. The drupes are sought by birds and other wildlife as well, so you had better get an early start. Little Mary is considered evergreen to about 25°F, and is root hardy to 20°F. In colder regions, the plant may be utilized as an attractive potted plant for the patio. Although considered very drought tolerant, the plant may shed leaves in time of extreme dryness. Good drainage is a must for this plant, otherwise it has few other requirements or problems. USDA Zone 9.
Manfreda
maculosa ![]() |
|
Texas Tuberose Ever since you were a kid, you've probably dreamed about finding
a cool plant with purple polka-dots. Manfreda maculosa will fulfill your
fantasy! This unusual member of the amaryllis family has linear, fleshy, unarmed
green leaves that are decorated with purple spots. Texas tuberose has a
symmetrical form similar to an agave, and sends up tall flower spikes in the
summer. The individual flowers start off creamy white, aging to a light purple
color. Hummingbirds are attracted to the tubular blossoms. It can be planted in
containers, or in the ground. Individual plants grow to about one foot tall and
wide, but form clumps quite rapidly. In fact, it could be planted at 2-foot
intervals to form a unique and hardy groundcover. Texas tuberose is a very
versatile and adaptable plant. It grows in clay or rocky soils, handles either
high or low amounts of irrigation, and thrives in full sun to full shade
exposures. However, the purple spots are more pronounced in sunny locations. In
the winter, the leaves will probably burn back to the ground, but new foliage is
produced in the spring from the underground tuber. Test plants in Denver have
recovered from temperatures as low as 10° F. USDA Zone 8.

Blackfoot Daisy Most people in the low deserts are aware of this tough little
perennial, but may not be aware that it recovers from temperatures down to -20°
F! The small white daisy flowers of Blackfoot daisy have yellow centers, and
cover the small mound of foliage during the bloom season. In low deserts the
flowering is heaviest in spring and fall, while summer is the showiest season in
the high deserts. The plant itself has narrow grey-green leaves, and grows to a
useful size of about 12 inches tall by 15 to 18 inches wide. The stems are quite
brittle, so it is not suited to high traffic areas. Plant Blackfoot daisy in
full sun, well-drained soil, and be careful not to over water. It is highly
tolerant of reflected heat exposures. It is reported to be deer resistant, but I
have no personal experience with this. Although deer may not eat it, I have
visions of their hooves smashing the brittle stems and killing it anyway. USDA
Zone 5.

Four O' clock Cascading over low walls or tucked between boulders, Four O' clock is a stunning groundcover. The rounded, succulent leaves are blue-green, giving a lush appearance. Frost will burn this foliage to the ground, but it recovers rapidly in the spring from a large tuber. During the summer it puts out masses of large, trumpet-shaped hot pink flowers. These blossoms open in late afternoon (hence the name Four O' clock), and close the next morning. Hummingbirds and hawk moths are attracted to the flowers. The seeds set after flowering are a favorite of desert birds. This long-lived perennial is native to New Mexico, Colorado, Arizona and Utah, and is hardy to -20° F. It will grow in full sun or part shade, but insists upon well-drained soil. Native Americans used the roots to induce visions. USDA Zone 5.

Muhlenbergia
capillaris Regal Mist™ ![]() |
|
This native of east Texas has taken the Southwest by storm in the past few
years. During their fall bloom period, mass plantings of Regal Mist™ can
literally stop traffic! The haze of deep pink flowers covering the plant is
especially stunning when backlit by the sun. Muhlenbergia capillaris is a small
clump grass with narrow, glossy green leaves. The foliage forms a dense rosette
to three feet tall and wide, with the frothy flowers adding another 1-2 feet of
height in the fall months. This fast-growing plant should be cut almost to the
ground in late winter or early spring to remove the brown leaves and spent
flowers. In cold regions it will turn winter dormant, but is hardy to -10° F.
Regal Mist™ thrives in full sun and reflected heat locations, and even
tolerates light shade. It is adapted to a wide range of soils, from sand to
clay, and survives drastic fluctuations in water supply. While it will survive
with very little water, it needs ample irrigation to look its best in the
summertime. To date, reseeding has not been a problem when plants are watered
with drip irrigation. Use Regal Mist™ in bold sweeps, nestled up against
boulders or low walls for a softening effect, or around water features and
swimming pools. USDA Zone 6.

Deer Grass Dependable and adaptable, Deer grass is the backbone of
many desert gardens. The lush green-grey foliage softens boulders, cacti, and is
ideal for use around water features. Native to the Southwest at elevations up to
7000 feet, Deer grass thrives in varied conditions. It flourishes in full sun
and difficult reflected heat exposures, and tolerates quite a bit of shade. Deer
grass is extremely drought tolerant, although the foliage browns out if adequate
water is not available in the summer. It also handles high rainfall, virtually
any soils, and is hardy to 0° F. In the fall it sends up slender tan flower
spikes that create a stunning contrast with the four to five foot mound of
luxuriant foliage. Since Deer grass can reseed if watered with overhead
irrigation systems, drip irrigation is recommended. USDA Zone 6.
