Mimosa-like fragrant fluffy cream blossoms after rains in late spring to summer, which attract bees. Reddish-brown seed pods. Leaves resemble those of Sweet Acacia, producing an open canopy and filtered shade. The cultivar was selected for more flowers and fewer seed pods.

Small-to-medium-sized slow-growing semi-evergreen tree with an airy graceful upright weeping habit and delicate open branching, slender when young but spreading elegantly with age. Distinctive smooth bark, white to reddish-yellow, peeling off and papery. May drop its grey-green leaves in a drought or cold spell. The lengthy needle-like leaf stalks remain prominently after the small leaflets drop, and hang gracefully from thin branches. Fragrant creamy-white flower spikes occur in late spring to summer, and occasionally throughout the year, followed by flattened seed pods. Wonderful visual accent tree with a picturesque silhouette, attractive bark, low maintenance requirements, and drought and heat resistance.

"Evergreen to semi-evergreen, slow-growing, large shrub to single-to-multi-trunked tree, with a widely-spreading crown. Silvery-grey bark, which becomes rough with age.

The tree was hybridized at the Arizona Sonora Desert Museum in Tucson, and is a genetic cross between Parkinsonia microphylla, Parkinsonia florida, and Parkinsonia aculeata.

Small-to-medium-sized deciduous tree with short, forking trunk and open, spreading crown of crooked branches.
