Neutral lmelling On Dec 10, 2004, lmelling from Ithaca, NY (Zone 5b) wrote:

From the sources "Hydrangeas for American Gardens," by Michael A. Dirr (2004), and "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press), this shrub has a spreading habit and grows up to about 6.5 feet. The leaves are velvety grayish. Flowers carry serrate white florets with three to four sepals; fertile flowers are lilac. This is a tender form that comes from Taiwan and is now considered a cultivar. Closely related to H. villosa. It flowers a month later than comaprable cultivars.

Produces deep violet fertile flowers surrounded by a few white sepalous clusters in 4s.
