Uncarina grandidieri is a most attractive plant. Deciduous shrub or small tree to 25ft, trunk up to 1ft in diameter. Abundant water when growing, keep on the dry side when dormant.
The flower resembles a large Petunia in form and is bright yellow with a dark throat, as in the Thunbergia alata. The stems are stout and become thickened with age. The hairy leaves resemble those of the cotton plant. They are sticky to the touch and yield a musty odor when rubbed. The leaves are deciduous during the winter resting season. Fruit has small inwardly pointed barbs mounted on 3/4in pedicels. Don't touch this fruit unless you want to spend some time trying to remove it from your fingers.
