Close to 200 species of shrubs and small trees from tropical America make up the Cestrum genus. Their tubular or funnel-shaped flowers are often fragrant (and sometimes night-scented). The flowers are followed by white, purple, or red berries.
Noteworthy CharacteristicsAll parts, including the berries, are poisonous.
CareProvide full sun or partial shade and fertile, well-drained soil.
PropagationRoot cuttings in summer. Start seeds of hardy species in a cold frame in fall, and seeds of tender species indoors in spring at 55-64°F.
ProblemsWatch for scale insects. Magnesium deficiency, rust, powdery mildew, fungal leaf spots, and dieback can also be problems.
