The Desert Ironwood (Tesota) is generally described as a perennial tree or shrub. This is native to the U.S. (United States) has its most active growth period in the spring and summer and fall . The Desert Ironwood (Tesota) has white-gray foliage and inconspicuous purple flowers, with an abuncance of conspicuous brown fruits or seeds. The greatest bloom is usually observed in the early spring, with fruit and seed production starting in the summer and continuing until fall. Leaves are retained year to year. The Desert Ironwood (Tesota) has a long life span relative to most other plant species and a slow growth rate. At maturity, the typical Desert Ironwood (Tesota) will reach up to 35 feet high, with a maximum height at 20 years of 20 feet.

The Desert Ironwood (Tesota) generally appears in field collections and doesn't tend to be commercially available. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 26°F. has high tolerance to drought and restricted water conditions.
