Snow Queen Oakleaf Hydrangea. This highly awarded selection by Princeton Nurseries is recognized for its upright panicles of pure white which fade to a light pink on a plant which matures to 6'. The fall color is a good burgundy on this selection which has become extremely popular in the nursery trade. It has great vigor. I have seen "Oakleafs" growing in almost full sun, but they are naturally an understory plant in the wild; hence, they perform at their best with good drainage and filtered sun. If shade gets too dense, this will hinder good flowering. If one has a heavy clay soil, it is best to plant these on a slope to insure good drainage.
