For the gardener

This melaleuca likes a sunny position with a moist (almost swampy) soil. It prefers the warm sub-tropical regions, although it can withstand light frosts. The plant will benefit from a light pruning and it can be made into a hedge.

It can be grown from seeds planted in the spring or from tip cuttings that are taken in the summer.
