[Overview]
Fleshy perennials or shrubs.
Some often have thick tubers.
The leaves are basal or alternate.
The flower heads are solitary or borne in corymbs; most are yellow, but some are white or purple.
The involucre is in one row.
The fruit is an achene with a pappus.
[Cultivation]
Propagate from seed, by cuttings, or by division.
Those with weak cold tolerance are brought indoors to a sunny spot in winter.
They prefer a sunny, airy, well-drained sandy soil.
Take care not to overwater; from spring to autumn water after the soil has dried, and in winter keep them even drier.
Shrubby types are especially weak in heat and humidity, so withhold water during the summer dormant period.
Go easy on fertilizer; a small amount of liquid fertilizer in spring and autumn is enough.
Pests include scale insects and aphids.
