In East Africa the flowers and leaves of Plumbago are used as a dye for textiles: beige, lemon, yellow (if combined with alum) or gold (if combined with chrome). Plumbagin is also a yellow pigment, occurring in a colourless combined form in the plant and is liberated by acid treatment. The sap of the roots is grey-blue, and is used for tattoos. The plant has insecticidal properties as an antifeedant and as a moulting inhibitor. Children often make 'earrings' with the sticky flowers - letting them stick to their earlobes.

The plant responds very well to pruning and so is often trained to form low hedges or borders and sometimes trained as a climber on arches.
