Positive lmelling On Dec 2, 2004, lmelling from Ithaca, NY (Zone 5b) wrote:

According to the authors of "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press), "A vigorous growing shrub up to 6.5' high and wide. Branches are weak, so plants are often untidy. Flowerheads are numerous, of medium size, with sepals packed together, pure white, serrrate, fading to light pink, and long lasting. Flowering occurs in June. This may be the best known white cultivar.

Other information: cold resistant; foliage turns red, orange and green in autumn.
