Hydrangea quercifolia Oakleaf hydrangea - is a native of the southeast United States that has been in cultivation since 1803. It is a stoloniferous 4-6 foot tall shrub with handsome coarse foliage. Fall color can vary, but generally is a flamboyant mix of red, orange and purple. The sterile showy white flowers conceal the small fertile flowers that occur in 4-12 inch long erect panicles. The June blooms are long lasting, slowly fading from white to a purplish-pink and finally in the fall to a brownish tan that can used in dried flower arrangements. Oakleaf hydrangea is propagated by seed, division, layering, cuttings and tissue culture. Cuttings do not tolerate too wet a root environment. Small plants are grown in containers. Landscape size plants are commonly field grown. Cultivars known for erect, showy flowers are 'Alice', 'Alison', 'Snowflake' and 'Snow Queen'.
