In the garden
Cestrum parqui is a semi-evergreen shrub native to South America that produces strongly scented flowers in the summer and autumn months. The floral display runs from July to October and is followed by persistent foliage through the growing season. As a genus member it brings a distinct scent profile to the border when in bloom. Plant this species where it receives full sun or light shade on a moist yet well-drained soil and protect it from cold winds; sheltered sites are recommended. Its UK hardiness is given as 8, so choose milder, protected locations rather than exposed sites. Water regularly during establishment and in dry spells to keep soil evenly moist but not waterlogged. In UK gardens it suits a warm border, courtyard or a sunny, sheltered wall where the scent can be enjoyed. Flowers are noticeable for their yellow-green tones and perfume, which makes it effective close to a path or seating area. Prune lightly after flowering to maintain shape and to remove any frost-damaged shoots. Handle Cestrum parqui with care: all parts are harmful if eaten, so wear gloves when pruning and keep plants out of reach of children and pets because all parts of Cestrum parqui are harmful if eaten.
