Flowers and Fruit: Male and female flowers on separate trees (dioecious). Non-showy flowers. Fruit is a small, non-showy pod and also not showy.
Natural and Adaptive Range: Native to China and Japan but adapts very well here in Texas to a variety of soils given some moisture and moderate fertility. It grows well in full sun but would benefit from afternoon shade.
Management: Relatively easy to grow but does need moisture. Does not handle drought and drying winds very well and tends to get leaf scorch in the heat of the summer in full sun especially in the afternoon. Possible Problems: Few that are serious. Occasional insects and burning from the heat of summer if the beds arenít healthy and mulched. Propagation: Seed primarily because cuttings are hard establish.
Notes: This is a good tree for people to use around swimming pools and in other areas where neatness is a factor. Katsura has no messy flowers, fruits or large leaves to create a maintenance problem. This is a tree that can stand some fairly moist soil. The foliage produces a wonderful chocolate aroma in the summer.
