Jessamine Cestrum

Cestrum is a genus of 232 accepted species of large flowering shrubs that are mostly evergreen and native to the warm temperate to tropical climates of Central and South America. They are members of the nightshade family (Solanaceae) and are commonly called jessamine due to their fragrant flowers. They may grow from 3 to 13 feet tall and equally as wide, depending on the species, and have clusters of small, colorful, tubular-shaped flowers. The genus name Cestrum originates from the Greek word kestron, meaning belt or girdle.

These plants prefer full sun to partial shade and moist, well-drained, loamy soil. In very hot climates, they will benefit from afternoon shade. They are heat and humidity-tolerant. These plants are winter hardy in zones 9 to 11. In North Carolina, consider growing as a container plant that overwinters indoors; however, the fragrance may be overpowering. Best propagated by stem cuttings in late summer.

Depending on the climate, these shrubs can be grown as evergreen, deciduous, perennial, or annual. They have a vase-shaped habit and branched, erect stems. The leaves are glossy, medium to dark green, and lanceolate, elliptical, or ovate. The flowers appear in clusters and are small, narrow, tubular, with flaring lobes. The colors of the blossoms range from creamy white, golden yellow, red or reddish-orange, yellow-green, pale green, or violet, and are dependent upon the species. The fruits are small green berries that ripen in various colors.

Cestrum species will add color and fragrance to a border, driveway, or entrance. Consider planting as an ornamental hedge or screen in warmer climates.

All parts of these plants are toxic if ingested. Keep this plant out of the reach of children and pets. Poisoning has been reported in cattle, sheep, goats, horses, and pigs.
