BUXUS MICROPHYLLA "JAPANESE BOXWOOD"
Japanese box or littleleaf box, is a species of flowering plant in the box family found in Japan and Taiwan. It is a dwarf evergreen shrub or small tree growing to 1 m (3.3 ft) tall and wide . A excellent choice for a sub-tropical that you can keep indoors year roun, as long as you provide a very cool window or other environment that will allow the plant to acheive a dormancy. By cool we mean any where from 35 degrees to 60 degrees while achieving a decent humidity level for a evergreen to maintain its foliage in a dry house.
Do not let this plant dry out completely as evergreens in general are not good convalescents if the foliage gets emaciated.
