Plant details

Also known as Lycianthes rantonnetii, this South American shrub is an outstanding conservatory plant, normally grown from cuttings although seeds of the species are sometimes available and germinate easily. It is a relative newcomer to garden use, and has quickly found popularity for its superb display of richly coloured and lightly fragrant flowers over a long season, provided it is grown in full sun. Water and feed regularly for the best display. Cuttings will make good-sized bushes for the following summer. The small red autumn berries are poisonous when ingested.
