CONSERVATION INFORMATION

DESCRIPTION

Growth Habit and Form

Tall stewartia grows 20 to 25 feet in height in as many years, its young pyramidal crown maturing into an open, multi-trunked form with somewhat horizontal branches.

Leaves

Leaves are alternate, simple, and elliptic to oblong-elliptic with saw-toothed margins. The 1.5 to 3-inch-long leaves are dark green above and grayish green and pubescent (covered with short soft hairs) below. The leaves cast light shade beneath this deciduous tree and develop outstanding deep red fall color.

Flowers

In June small, cupped flowers appear, opening over a four-week period. Flowers are 1 to 1.5 inches wide, white with yellow stamens, and subtended by large leafy bracts. Flowers tend to remain cupped and do not open as wide as Korean stewartia (S. koreana) and Japanese stewartia (S. pseudocamellia)

Fruit

Fruit is a 5-valved, ½ inch long, woody, beaked capsule covered with hairs.
