Cercidium Hybrid ‘AZT’ exhibits qualities found in Palo Brea, Blue and Mexican Palo Verde. The canopy is lush green, provides ample shade and intricate branching patterns. The characteristics that set this ‘AZT’ clone apart from seed selections are distinctive rich green trunks and the versatility to be grown as either V-shaped upright or candelabra form specimens, the absence of thorns, and a semi-evergreen growth. Like Palo Brea, branches remain smooth and dark green as they mature. Brilliant yellow flowers that are abundantly in spring and intermittently during the summer months. 'AZT' has 4 to 6 pairs of leaves with 15 to 24 pairs of leaflets per leave. These highly divided leaves produce a canopy that is lush yet airy and provides filtered shade that promotes flowering of under-story shrubs and groundcovers. It can be used as an accent tree, along
street and parking medians, as a focal point, single specimen or any application that requires a striking, graceful, thornless desert tree.

 Several years ago Arid Zone Trees (AZT) began vegetatively propagating (cloning) some of our most popular desert adapted tree species. This process involved: 1) identifying trees that had both desirable physical qualities (branching habits, leaf color, leaf canopy, and flower color) and sound horticultural characteristics (rooting, cold hardiness and growth rate); 2) developing propagation techniques that allowed the large scale vegetative propagation of the selected trees; and 3) growing these selections to market sizes for additional nursery evaluation and field testing in landscape setting. This tree is the product of our research and evaluation. We have identified each of our clone species with the variety designation ‘AZT’. We believe this is the best and
