The fruit is a double lionfish with two seeds, each seed is 4-7 mm in diameter, with a 15 mm wing; the wings are elongated and often overlap.It is widely used in temperate regions as an ornamental plant. It was introduced in Japan for a long time, where its name is translated as "Chinese maple". Introduced in Europe and North America much later, in 1896, and now it is sometimes grown in parks and large gardens. Adult specimens can be found at Westonbirth Arboretum in England, Esveld Aceretum in Boskoop, The Netherlands, Arnold Arboretum in Boston, and many other places. The tripartite maple is a popular choice for bonsai construction and responds well to the use of leaf reduction and pruning techniques.
