This U.S. native shrub has glossy, dark green leaves. Bowl- or cup-shaped pink to white flowers are borne in large clusters from late spring to midsummer.

This cultivar produces 8-inch-long, conical flower heads from early summer on. It is as notable for its distinct, deeply lobed leaves as for its reliably showy, creamy blooms. The foliage produces outstanding fall color and the flowers take on purplish-pink hues when dried.

Oakleaf hydrangeas originated along the sandy streams of the southeastern United States, and they are more drought tolerant than many other hydrangeas. Their matte green leaves are coarsely textured and deeply lobed, and in fall they turn red and purple. White flower heads form in spring, and as summer draws to a close they turn shades of pink, green, and ecru.

The white of this rose has a purity of color that is without equal. It produces semi-double, very fragrant flowers from spring to fall, which are sometimes followed by orange hips. It grows to 6 feet high and wide.
