Ceratostigma (/ˌsɛrətoʊˈstɪɡmə, sɪˌræt-/;[2][3]), or leadwort, plumbago, is a genus of eight species of flowering plants in the family Plumbaginaceae, native to warm temperate to tropical regions of Africa and Asia. Common names are shared with the genus Plumbago.
Description[edit]
Ceratostigma species are flowering herbaceous plants, subshrubs, or small shrubs growing to 0.3–1 m (0.98–3.28 ft) tall. The leaves are spirally arranged, simple, 1–9 cm long, usually with a hairy margin. Some of the species are evergreen, others deciduous. The flowers are produced in a compact inflorescence, each flower with a five-lobed corolla; flower colour varies from pale to dark blue to red-purple. The fruit is a small bristly capsule containing a single seed.[citation needed]
