plant sale text: Smooth Hydrangea is a small deciduous shrub that bears numerous flowers in showy cymes. Its flowers change color over time, progressing from pale green to creamy white to brown. Mature plants eventually develop handsome exfoliating bark that is attractive year-round. This native species grows best when it is planted in moist, well-drained soil in part shade. It is found growing in rich woods and on shady rock ledges in the piedmont and mountains. The bark and leaves were used by the Cherokee tribe for medicinal uses.
