The leaves turn red or yellow in autumn.
The flowers are borne 15–20 in compound corymbs at the branch tips, with male flowers and bisexual flowers blooming on the same tree.
The flowers have 5 sepals and 5 petals.
The petals are pale yellow, and the sepals are pale yellow, sometimes tinged with purple.

Partial shade is better, especially while the tree is young.
In shade, the autumn color develops poorly.
Longhorn beetles and aphids cause damage, so kill them as soon as they are found.
