Cestrum is a genus of flowering plants in the nightshade family, Solanaceae. These plants are known for their fragrant flowers, which often bloom at night and attract pollinators like moths. Cestrum species can be found in tropical and subtropical regions, and they are commonly used in gardens for their ornamental value. Some popular species include Cestrum nocturnum, also known as night-blooming jasmine, and Cestrum parqui, or Chilean jasmine. These plants can grow as shrubs or small trees and are typically easy to care for, thriving in well-drained soil and full sun. However, some species can be invasive in certain areas.
