Cayenne pepper, is a short-lived evergreen shrub usually 1 to 1.5 m in height and 1 to 3 cm in basal stem diameter. The shrub is supported by a short to long taproot (depending on soil conditions), many spreading lateral roots, and moderately abundant fibrous roots. The stem and larger branches of mature plants are woody but moderately soft and weak. Bark of stems and older branches is light gray. The form is upright, the
abundant branching is often dichotomous, and the branches and twigs are slender. The ovate to ovate lanceolate
leaves vary in size. The larger of them are 4 to 12 cm long and 1 to 4.5 cm broad. Greenish-white to yellowish-white flowers with blue, violet, or yellow anthers occur in groups of two or more at the nodes. The berries are red or red-orange at maturity, elongated with a pointed or rounded tip, 1.5 to 3.5 cm long and 0.5 to 1.2 cm thick. The fruits are somewhat dry and contain few to many (depending on fruit size) cream to yellow lenticular seeds about 3 mm in diameter. The fruits, especially the seeds and placenta, have a biting, pungent taste.
