The blooming period occurs during mid-spring for about 1-2 weeks. The slender pedicels of the flowers are longer toward the base of each raceme (up to 1½" long), becoming shorter toward its tip (up to ¾" long). The calyx is light green with woolly hairs its teeth are much shorter than the petals. Individual flowers are about 1" across, consisting of 5 white narrow petals, a short tubular calyx with 5 teeth, about 20 stamens, and a pistil with a single style. These racemes develop a little before or at the same time as the first emergence of the leaves. Racemes of 6-14 flowers develop at the tips of shoots they are 3-7" long. The slender petioles are ¾-1½" long and light green they are covered with woolly hairs while young, becoming more glabrous with age. Leaves become less hairy as they mature: At maturity, their upper sides are medium green and glabrous, while their lower sides are either sparsely covered with woolly hairs, or the hairs are largely concentrated along their central veins. Young leaves are densely covered with woolly hairs, particularly along their undersides. These leaves are more or less ovate in shape and finely serrated along their margins the bases of these leaves are either rounded or slightly cordate. Alternate leaves up to 4" long and 2" across occur along the shoots and young twigs. Young leafy and flowering shoots are green and they are more or less covered with woolly hairs. Branch bark is smooth and gray, while twigs are some shade of brown and glabrous. Trunk bark is gray, developing shallow furrows and flat ridges on older shrubs or trees. If there is a single trunk, it is 6-16" across near the base and short. Description: This is a multi-stemmed shrub or small tree about 10-30' tall, forming an irregular crown that is usually more tall than wide.
