Mexican holdback is a small tree typically about 15 feet tall but can be twice that mature; it may also grow as a large shrub. The crown is moderately dense, rounded, usually spreading to 1/2 to 1/3 its height. Evergreen leaves are alternate, bipinnate with round leaflets about 2 inches long. Flowers are produced on a terminal spike 3-6 inches long, bearing clusters of yellow, fragrant flowers which persist for several months and attract hummingbirds. Fruits are dry, hard, pale green then brown, somewhat curled pods 3-6 inches long containing several seeds. The tree is seed propagated. In cultivation, mexican holdback grows well on a variety of soil types providing they are well-drained and is not generally affected by pests. The plant needs to be trained to achieve and maintain a tree form. The attractive leaves and showy blooms make this a good choice to grow near a patio or deck, in above ground planters, and as an accent or specimen tree. It can also be grown as a hardy, colorful shrub border or parking lot buffer strip.
