(Sweet Acacia, Texas Huisache)
The soft airy look of this small acacia leaves little clue to its adaptation to North America’s hottest desert climates. Its natural range extends from the American southwest into Mexico, then it has adjunct populations far south in Chile. It is one of the desert acacias that bear sharp thorns to protect themselves from browsing wildlife. The leaves are medium green, very small and fern like.
This tree blooms in early to mid spring with large pompon-like bright yellow flowers that are markedly...

(Australian Blackwood, Blackwood)
One of the largest and most cold-hardy acacias in cultivation, this vigorous, medium-sized tree is valued for its toughness, attractive evergreen foliage, and fragrant spring flowers. Native to cool, moist locations in eastern Australia and Tasmania, it rapidly forms an upright tree whose brittle branches are furnished with finely textured, pinnate leaves,or with crescent-shaped, gray-green, leaf-like "phyllodes" (which are actually expanded leaf stems). Mature trees cast moderate to dense shade....
(Myall Acacia, Weeping Acacia)
Weeping acacia is a medium-sized evergreen tree with airy, pendulous branches. It originates from Australia and has attractive gray-blue, linear phyllodes (flattened leaf stalks) and deeply fissured orange-red and gray bark. In winter it produces small, round, pale-yellow flowers, which are followed by flatted green pods that age to brown.
Weeping acacia is highly drought tolerant and requires full sun and moderately fertile, acidic to neutral soil that is perfectly drained. It makes a fine specimen...
(Bank Catclaw, Trailing Acacia)
This groundcover acacia has proven its value time and again as a first class slope coverage for hot dry banks. In the western United States it is commonly planted in tough locations adjacent to commercial sites and freeways.
Trailing acacia is a native of eastern Australia and is the most widely used prostrate species around the world. Plants bloom in spring with pea-sized yellow puff balls that are concentrated at the base of the leaves along the stems. Its leaves are blue-green, long and densely...
Truly uniform growth make this low-growing, uniform clone far more reliable than standard Acacia redolens. In the western United States it is commonly planted in tough locations adjacent to commercial sites and freeways.

(Ever-blooming Wattle, Silver Wattle, Water Wattle)
Bearing its sunny fragrant flowers nearly year-round, this fast growing evergreen shrub or small tree is also noteworthy for its attractive foliage and its adaptability.
In spring large sprays of small golden pompon-like flower heads bow the spreading branches of this acacia, attracting numerous bees. The flowers are nicely complemented by the narrow, willowy, gray-green "leaves", which are actually expanded leaf stems known as "phyllodes." Sporadic rebloom occurs throughout the year if temperatures...
(Cooba, Willow Acacia)
This acacia has a weeping habit and willow-like foliage, hence the common name. Like many acacias, it is adapted to hot, arid conditions and is very tough. It’s found across much of Eastern Australia in sunny thickets and open areas. In time it becomes a upright tree with a large dense canopy. It has a tendency to sucker, like willows do, which can be problematic in the landscape.
The leaves of willow acacia are long, thin and dark green. It bears clusters of pea-sized flowers that are fragrant,...
(Blueleaf Wattle, Golden Wreath Wattle)
This fast-growing tree is ideal for arid climates where many others will not grow. Golden wreath wattle offers clusters of golden flowers in the spring and an informal but appealing look the rest of the season. It is native to southwestern Australia where it inhabits open plains and rugged lands.
When mature it develops a spreading crown with low branches. Its blue-green leaves are long and narrow, almost needle-like, and widely spaced on the branches. In spring it becomes covered with fragrant...

(Dalby Myall, Shoestring Acacia)
Shoestring acacia has proven its amenability to the harsh low desert where it grows as a graceful, wispy accent or shade tree. It is native across most of Australia, which explains its adaptability to a wide range of soil types and harsh climates.
Its very narrow, waxy green leaves are long and dangle, giving this tough, drought-tolerant tree an unusually delicate and graceful appearance. Its spring blooms are small, pea-sized and shaped, cream-colored and borne in drooping clusters. These are...
(Copperleaf, Copperplant, Wilkes' Acalypha)
An evergreen shrub native to the Pacific islands, copperleaf bears brightly colored foliage in shades or red, purple, bronze and green. It is a popular landscape plant in subtropical and tropical zones and planted as a houseplant or annual in cooler zones. The name, Acalypha wilkesiana, honors Rear Admiral Charles Wilkes, an American Naval Officer who explored the South Pacific during the mid-1800s.
Beautiful, mottled leaves are the reason copperleaf is so popular in the garden. They...
