Australian Mint Bush
Australian natives with minty smelling foliage and an enormous profusion of small flowers, usually in shades of purplish blue or white. Although they tend to be short-lived, they grow quickly and put on a good show. Prune them carefully; avoid cutting into bare wood or doing any other hard pruning. There are many species available; look for them at specialists’ nurseries or at plant sales held by botanical gardens. These plants require excellent drainage.Prostanthera rotundifolia
