The species include [[herbaceous]] plants and [[shrub]]s which grow to 0.5-2 m tall. The [[leaf|leaves]] are arranged spirally, simple, entire, 0.5-12 cm long, have a tapered base and often a hairy margin. [[Flower]]s can be white, blue, purple, red, or pink, with a tubular corolla and with five petal-like lobes; they are produced in [[raceme]]s.

The flower [[sepal|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.
