Culture

Best with regular moisture, although established trees develop some drought resistance. Trees will self-seed somewhat aggressively.

Noteworthy Characteristics

Chinese parasol tree is a small to medium-sized upright deciduous tree with a rounded crown. It is native to China, Korea, Japan and southeast Asia. It was introduced into the U. S. in the 1850s, and has naturalized over time in the Southeast from Virginia to Florida and Texas as well as in California. It typically grows 30-45’ tall. It is perhaps best noted for its very large, palmately-veined, 3-5 lobed leaves (to 12” across) that are bright green above and pubescent below. Leaves turn an undistinguished yellow in fall. Mildly fragrant, star-shaped, yellowish-green flowers (to 3/4” wide) in long terminal panicles (to 12”) bloom mostly at the twig ends in early summer. Flowers give way to leathery capsules that split open when ripe (autumn) into 4 or 5 sections, each section containing 1 to 3 seeds. Smooth greenish bark on the young branches and trunk is somewhat unusual. Genus name honors Karl Joseph von Firmian (1716-1782), Austrian statesman. Specific epithet is in reference to the simple (as opposed to compound) leaves. Additional common names for this tree are varnish tree (seed pods release a brownish, varnish-like fluid as they open) and phoenix tree (supernatural phoenix bird of Chinese legend perched on Firmiana trees). Synonymous with and formerly called Firmiana platanifolia.

Problems

No serious insect or disease problems.
