Hoheria

摘要

There are around 400,000 species of plant in the world right now—an incredible number. However, when it comes to cultivated plants it seems as though you hear certain genus names over and over again. Hoheria is not one of them.It is a little-known genus of New Zealand natives that are perhaps not widely grown because they are seen as not very hardy—the evergreen forms especially need a mild, sheltered location.There are five species, all shrubs or small trees in the mallow family (Malvaceae). Some are deciduous (H. lyallii Award of Garden Merit (AGM) and H. glabrata), some evergreen (H. sexsrylosa) and some semi-evergreen. The deciduous types are hardier thanthe evergreens, coping down to -15°C. H. populnea is much more tender, only tolerating down to -5°C.
