An evergreen semiclimbing shrub, cestrum makes a good plant for the greenhouse or sunroom, where it can be trained to a permanent support. It has oval leaves up to 3in/8cm long, which smell unpleasant.
Flowers are borne in clusters in summer and they too have an odor that some find unpleasant; it is strongest at night. Each bright yellow-orange bloom has a 3/4-in/ 2-cm-long tubular corolla with five pointed petal lobes at the mouth. The flowers are followed by white berries.
Cestrum elegans ‘Smithii’ has apricot pink flowers and blooms all year-round;
C. nocturnum, night-blooming jasmine, has white flowers.
HEIGHT To 10ft/3m.
POTTING MIX Soil-based with good drainage.
REPOTTING In spring, when the roots have filled the current pot, move a young plant into a pot one size larger.
PROPAGATION Sow seed in spring, or take stem cuttings with a heel in late summer.
KEEPING PLANTS Pinch off the growing tips of a young plant to encourage bushiness. And cut out a third or so of the oldest wood in the fall to ensure good flowering during the following year.
