These American desert natives add their own personalities to a landscape scene. Formerly classified as Cercidium, Parkinsonia are easily recognized due to their blue-green to green bark, naturally occurring multiple trunks and distinctive elegance. Most are wide spreading from 25 to 35 feet with a similar height, which varies according to the species, moisture and soil type. Masses of yellow flowers cover the trees in April and early May. All tolerate extremes of heat, sun and soil type, although they do best in well-drained soils.
