Acer triflorum, or the three flowered maple, is a non-native species originating from northeastern China and Korea. It prefers acidic soil and is salt tolerant, but is intolerant of alkaline soils, soil compaction, and wet soils. It prefers sun to partial shade, and does best in moist, but well-drained soils. This species is not commonly available in nurseries due to its complex seed dormancy and limited success with cuttings, but may become popular in the future due to its aesthetic features. It is one of the few trees to develop good fall colour in shade.
