The Littleleaf Leadtree (Retusa) 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 summer and fall . The Littleleaf Leadtree (Retusa) has green foliage and inconspicuous yellow flowers, with an abuncance of conspicuous blue 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 not retained year to year. The Littleleaf Leadtree (Retusa) has a moderate life span relative to most other plant species and a rapid growth rate. At maturity, the typical Littleleaf Leadtree (Retusa) will reach up to 25 feet high, with a maximum height at 20 years of 12 feet.

The Littleleaf Leadtree (Retusa) is usually not commercially available except under contract. It can be propagated by bare root, container, cuttings, seed. It has a slow ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 12°F. has high tolerance to drought and restricted water conditions.
