Cestrum aurantiacum: The Orange Cestrum

The Yellow Shrub Jessamine

Cestrum aurantiacum, known as Orange Cestrum or Yellow Shrub Jessamine, is a flowering shrub native to Guatemala and Honduras. Its tubular orange-yellow flowers and extended bloom season make it a valuable addition to warm-climate gardens.

Botanical Classification

Continuous Orange-Yellow Trumpets

This evergreen shrub grows 6-10 feet tall and wide with lanceolate, glossy green leaves. The flowers are tubular, 1-1.5 inches long, in clusters at branch tips, opening orange and aging to yellow—creating a two-tone effect. Blooms appear from spring through fall, often year-round in frost-free areas. Sweetly fragrant, especially at night.

Orange Cestrum thrives in full sun to partial shade with well-draining soil. Regular water for best bloom; drought-tolerant once established. Hardy in zones 9-11; in zone 9, may die back but resprouts. Prune after flowering to maintain shape.

Night-Fragrance Garden Asset

Plant near patios, windows, and evening seating areas where the nocturnal fragrance can be enjoyed. The orange-yellow flowers attract hummingbirds and night-flying moths. Use as a specimen, informal hedge, or in mixed borders. A reliable, long-blooming shrub for subtropical and tropical gardens.
