Description
editLiquidambar formosana is a large, native, deciduous tree that grows up to 30-40m tall. The leaves are 10~15 cm wide.,[4] and are three-lobed unlike five- to seven-lobed leaves of most American Liquidambar species.[5] The foliage of the L. formosana turns a very attractive red color in autumn.[6] Leaves grow in an alternate arrangement, and are simple, palmately-veined, with serrated margins. Roots can be aggressive and branches are usually covered with corky projections. The individual flowers of L. formosana are unisexual. However, both sexes can be found in the same plant (monoecious).[7] Male flowers are in catkins, female flowers form dense spherical heads, and the fruit is burr-like because of the persistent styles.[6]
Distribution and habitat
editLiquidambar formosana grows mostly in woodland in warm temperate zones. It requires moist soil and can grow in light to no shade areas.[3] It is found in Hong Kong, Central and Southern China, South Korea, Taiwan, Laos and Vietnam.[4]
