The Common Sweetleaf (Tinctoria) 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 Common Sweetleaf (Tinctoria) has green foliage and inconspicuous yellow flowers, with a moderate amount of conspicuous purple fruits or seeds. The greatest bloom is usually observed in the spring, with fruit and seed production starting in the summer and continuing until fall. Leaves are retained year to year. The Common Sweetleaf (Tinctoria) has a short life span relative to most other plant species and a rapid growth rate. At maturity, the typical Common Sweetleaf (Tinctoria) will reach up to 19.7 feet high, with a maximum height at 20 years of 30 feet.

The Common Sweetleaf (Tinctoria) generally appears in field collections and doesn't tend to be commercially available. It can be propagated by seed. It has a slow ability to spread through seed production and the seedlings have low vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -15°F. has medium tolerance to drought and restricted water conditions.
