Description The Desert Ironwood grows as a bush or tree and reaches heights of about 10 metres (33 ft), and average trunk diameters of about 60 cm (24 in); in exceptional sites in larger protected washes, greater height and more massive.In younger trees, the bark is gray, shiny, and smooth; in older trees the bark is broken open. The tree is an evergreen plant , but can lose its leaves if temperatures fall below 2 °C (36 °F). In continual drought conditions leaves will be lost.Leaves are bluish-green and pinnate compound. Leaves are arranged on a petiole, 6 in (15 cm) long, with 6-9 leaflets-(or variously up to 15, 7, 7-opposite, and one terminal), each being 0.7 to 2.5 cm (0.28 to 0.98 in). At the base of each pinnate leaf petiole grow two thorns, about 1 cm (0.39 in) long.Bloom time occurs in late April/May to June. Flowers are of 5 unequal petals, in colors of medium purple, magenta-red, or also white to pale pink. Seedpods are 5-8 cm (2-4 in) long, and light reddish brown. When seedpods are ripened two other species Parkinsonia florida -( Blue Palo Verde ), and Acacia constricta -(Catclaw Acacia) have similar light red brownish colors.
