Silver-leaved hydrangea is an attractive shrub native to Appalachia. It has lacecap clusters of flowers in early summer that emerge green and change to white. Its distinctive characteristic is the silvery underside of its leaves. Silver-leaved hydrangea is somewhat sensitive to drought, so it needs a site with moist soil. The plant pictured here is the cultivar 'Samantha'.
