The flowers are bell-shaped and pentamerous. There are about 150 species distributed from southern America to northern Argentina, of which about 100 species grow wild in Mexico. They are cold-resistant and hardy, and there are many horticultural varieties. They are used in flower clocks and rock gardens. They are propagated by leaf cuttings.
