CINERARIA

any of several ornamental plants that have been developed by florists from species of the genus Senecio of the composite family (Asteraceae). There are two distinct types: the garden species, especially dusty miller (S. cineraria); and the greenhouse varieties of S. cruentus, commonly referred to simply as cinerarias. Greenhouse cinerarias may be dwarf, compact-growing plants with large flowers in dense clusters, or taller plants with larger, more spreading clusters of small star-shaped (stellate) flowers. Both types are easily grown from seed and are sold commercially as potted plants in a variety of colours.
