Peppermint Tree is a very useful tree in temperate coastal areas as an evergreen specimen or shade tree. It tolerates heat but not extreme cold. Its attractive weeping character and dark green foliage are quite pleasing. It prefers moist, sandy soils. Stems have a distinct zig-zag characteristic. Branches may tend to break in very windy areas. It may eventually require regularly scheduled light top-trimming (but not necessarily shearing) of vigorous top shoots to maintain its height below 25'.
Has fragrant Leaf.
Native to Western Australia.
