About
Cestrum elegans, the purple cestrum, red cestrum, or bastard jasmine, is a species of flowering plants in the genus Cestrum.
How to grow it
Propagate by cuttings of half-ripe shoots in summer and root with slight bottom heat. Grow in rich, light soil. Requires moist soil; if potted, water every few days, but no more than twice a week. Soil needs to remain moist but not water-logged. Seeds are dispersed via birds and forms of soil movement including flooding. Enjoys half-sun, half-shaded areas and will require pruning to encourage growth and strength. Overwinter in a cool spot exposed to a lot of sun.
Uses
Typically grown in a greenhouse, where it will grow up pillars or rafters, also grown as a wall shrub in sheltered gardens. Often grown in conservatories and cool glasshouses or in hanging baskets. Grows best in large containers when being trained to grow up a large object such as a pillar. Very suitable as an ornamental plant. Rather drought tolerant. Will attract many pollinators and hummingbirds.
