    Grown for their strong fragrant flowers. Clethra is an upright, deciduous, slow growing shrub that suckers close to the mother plant, forming a dense clump that usually gets 4-6' tall. Leaves are oval, mid-green and turn yellow in autumn. In late summer small bell-shaped flowers appear on 4-6" upright racemes and last up to six weeks. We have several large bushes of it in our gardens here, and it is a beautiful sight in late summer when the season is winding down. Full sun to part shade.
