It will form into a large shade tree as a specimen plant although we do think that trees always look better in copses or woodlands so plant plenty if you have the room in your garden. The Katsura Tree does respond well the pruning so it could also be used as an excellent deciduous hedging alternative to Fagus sylvatica (Copper Beech). Plant in temperate or mountainous areas as it is frost tolerant and insure that it gets irrigated during the drier periods of the year.
Again another tree that has lots of potential with not many growers propagation them. We are always open to talk to growers on new tree varieties and as designers we really need to get some alternatives out there so we can start experimenting!
