Plumbago auriculata, also called Plumbago capensis, Blue plumbago, Cape blumbago or Cape leadwort, is a well known plant.

Plumbago auriculata grows fast and to 2 meters (6 feet) tall. It has light blue to blue flowers and also variations with white (Plumbago auriculata var. alba) or deep blue (Plumbago auriculata 'Royal cape') flowers. The leaves are green and grow 4-8 cm (1.5-3 in) long. Native to South Africa.

It grows well in a container outdoors and can be watered freely in the summer. To get the flowers to appear, the plumbago requires a warm place in full sun or partial shade.

Var. alba, Hort., has white fis.—A well-known greenhouse plant. Old plants turned into the soil in late spring in a sunny exposure bloom profusely until frost. Plants struck from fall cuttings also give good bloom the following summer, but younger plants usually do not bloom so well. Plants can be kept in a cellar during winter, or they may be grown under glass for spring and summer bloom. It is an excellent rafter plant. In S. Calif, it climbs trees 15-20 ft. high if undisturbed. P. capensis and the white-fid, varieties are the commonest kinds. The above text is from the Standard Cyclopedia of Horticulture.
