Acacia greggii
Large mounding shrub to medium-size tree native to the Sonoran Desert. We select for the tree form, which is a cold-hardy substitute for Ironwood. Gray-green, feathery foliage hides catclaw thorns.

Acacia smallii
Usually multi-trunk tree to 20' high and 15'-20' wide with evergreen to semideciduous fernlike leaves. Pleasingly fragrant golden puffball flowers cover the trees in spring and sometimes in fall. Frequently used in medians, along roads and commercial landscapes. Hardiness varies with seed source.

Cercidium floridum
Beautiful bright yellow flowers cover the Blue Palo Verde in April. The blue green foliage and bark are distinctive and lend to its use as an accent tree in patios, residential, commercial, medians and roadsides.

Chilopsis linearis "Lois Adams"™
Kelly Green Trees developed this almost seedless cultivar. It has beautiful clusters of magenta, trumpet-shaped flowers which are frequented by hummingbirds and bloom from spring through first frost. Either a standard or multi-trunked tree, it is good in medians and along roads or as an accent tree. A Sonoran Desert native, it is thornless and compatible with many landscape styles.

Fraxinus velutina "Fantex"™
The Rio Grande ash is a large deciduous shade tree. This selection of Arizona ash distinguished by large glossy green foliage and early spring leaf break. The vase shaped canopy makes it appropriate for streets, parks and outdoor living areas.
