The species include herbaceous plants and shrubs growing to 0.5–2 m tall. The leaves are spirally arranged, simple, entire, 0.5–12 cm long, with a tapered base and often with a hairy margin. The flowers are white, blue, purple, red, or pink, with a tubular corolla with five petal-like lobes they are produced in racemes.The flower calyx has glandular trichomes, which secrete a sticky mucilage that is capable of trapping and killing insects it is unclear what the purpose of these trichomes is protection from pollination by way of crawlers or possible protocarnivory.Mature plumbago leaves often have a whitish residue on their undersides, a feature that can confuse gardeners. While this white material resembles a powdery mildew disease or a chemical spray deposit, it is actually a natural exudate from chalk glands that are found on the Plumbago species
