Plumbago is a genus of 10-20 species of flowering plants in the family Plumbaginaceae. Plumbago and leadwort (names which are also used by the genus Ceratostigma) are the most popular common names.
The species include herbaceous plants and shrubs which grow to 0.5-2 m tall. The leaves are arranged spirally, simple, entire, 0.5-12 cm long, have a tapered base and often a hairy margin. Flowers can be white, blue, purple, red, or pink, with a tubular corolla and with five petal-like lobes; they are produced in racemes.
The flower calyx has glandular hairs, which secrete a sticky mucilage that is capable of trapping and killing insects. The purpose of this secretion is not clear.
The name Plumbago is derived from Latin plumbum ("lead"), either from the lead-blue flower colour of some species (OED), or from the plant at one time being a supposed cure for lead poisoning (Huxley 1992).
Native to warm temperate to tropical regions of the world.
