Three Colours on One Leaf
This cultivar carries narrow, arching leaves marked with cream stripes, and as those leaves age the margins deepen to crimson, giving the plant its three-colour name. It grows as an erect shrub with only sparse branching, a slightly more upright and architectural habit than the plain species. The RHS recognises it with an Award of Garden Merit, a mark of its reliable garden and houseplant performance.

Watch Under Glass
Grown under glass, this cultivar can draw red spider mite and scale insects, the same sap-feeders that trouble dracaenas generally. It is otherwise described as generally free of disease.

Rarely Needs Pruning
Unlike dracaenas grown for shaping into bushy or standard forms, 'Tricolor' is noted as needing no routine pruning. If growth does turn weak, it can be cut back hard, to within about 15cm of the base, in spring to renew it.
