Wyalong wattle (Acacia cardiophylla), a member of the Fabaceae family, originates in the Riverina area of New South Wales, where it grows on central and southwestern slopes and open plains, especially in moist locations and on stream banks in red, sandy loams or gravelly clays, which provide good drainage. Hardy to 20 degrees Fahrenheit, it is an erect, spreading, multi-stemmed shrub or small tree that reaches 10 to 12 feet in height. Its dark gray bark is smooth and sometimes mottled with brown, with obscurely angled branchlets that soon become terete (circular or cylindrical), with spreading, stiff, cream-colored hairs. The feathery foliage is pale green with cream-colored tips. Masses of bright yellow heads of ball-shaped flowers are borne in the leaf axils in racemes (flower clusters with the separate flowers attached by short equal stalks at equal distances along a central stem) of up to 20 or more heads.
