Senecio: Greenhouse Plants
C – cool, minimum of 7°C (45°F)
This is a large group of plants with well over 1000 species. It therefore comes as no surprise that the choice of species for growing under glass is quite diverse. Senecio macroglossus ‘Variegatum’, is a variegated leaved climber which at a casual glance looks just like a rather succulent ivy. It is extremely attractive with the leaves being offset by deep red stems. Heads of rich yellow flowers are produced during winter. It has its origins in South Africa and is known as Cape Ivy. S. grandifolius from Mexico really is an imposing plant. It will reach 2 m (6 ft) in height and has large wide toothed leaves. Heads of bright yellow flowers appear in winter after thehave finished and give a reliable display. When plants become too large they can be cut down and will sprout up again. Cuttings, although large, will root easily in spring and summer. S. rowleyanus from SW Africa is the String of Beads Plant and is a remarkable succulent that looks very well trailing over the edge of a hanging basket, the leaves being almost spherical and of a pale green. White flowers are produced from September to November.
