LET820 Sweet Acacia ( Acacia smallii )
Sweet Acacia is currently one of the most popular residential trees being planted across the southern states, and for many good reasons! Its compact size and tolerance of ridiculous heat and poor soil make it useful for almost any situation; residential, commercial or otherwise. The real reason for this tree's popularity, however, is the abundant display of extremely fragrant, golden yellow puffballs in early spring.
Hardy to zone 7.

D7811 Blackwood Acacia ( Acacia melanoxylon )
A very quick-growing upright tree to 40 feet tall or much more with about a 20 feet width and, in maturity, an oval shaped crown. It has rough dark gray bark with vertical fissures and mid-green leaf-like flattened stems, called "phyllodes", that are 3 to 5 inches long by about an inch wide, with one margin straight and the other slightly curved.
Small creamy white flowers are in a small ball-like cluster from late winter into spring and are followed by thin curling seed pods that hang in brownish sheaves. Plant in full sun to light shade in soil with fairly good drainage. Hardy to 15-20 degrees F and tolerant of heat, alkalinity and coastal conditions. A durable tree for quick growth, screening and erosion control. While useful for screeding, its aggressive roots can lift sidewalks, damage foundations and plumbing and together with leaf, seed pod and branch litter and its propensity to sucker and reseed, so it is not ideal for street plantings.
It was highly recommended for street tree plantings in California prior to the 1940s, so it is still fairly commonly seen and in Southern California is not seen as an invasive plant. This tree comes from coastal areas of southeastern Australia where it grows from sea level to 3,500 feet in solitary stands in cool temperate rainforests or as an understory to larger Eucalyptus.

TRN677 Sweet Thorn ( Acacia karroo )
This small to medium, rather short-lived tree has a rounded crown to about 30 feet tall with finely pinnate leaves, long, white thorns and masses of yellow flowers in small, spherical heads, followed by narrow, flat pods. It is widely distributed in various types of savannas in southern Africa on sandy soils.
It makes a beautiful, drought tolerant ornamental for dry tropical and some warm temperate climates. As is common in acacias, edible gum seeps from cracks in the tree's bark, and is an important part of the bushbaby's winter diet. The gum can be used to manufacture candy (see Gum arabic) and used to have economic importance as "Cape Gum". In dry areas, the tree's presence is a sign of water, both above and underground.
The tree is especially useful as forage and fodder for domestic and wild animals. Apparently, there is no risk of poisoning from it. Goats seem to like V. karroo better than cattle. The small pom-pom shaped yellow flowers are attractive in mid-summer. The flowers make it a very good source of forage for honey bees; honey from it has a pleasant taste. Zone 9 or higher.
