Gardeners' Notes:


On Dec 3, 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):

Both call this a smaller plant but can grow up to 5' tall, but normally around 4'. Flowerheads have many ray-flowers with fewer sterile florets. Flowers early and appear almost a month earlier than other H. paniculata cultivars, the white sepals age to rose, sometimes by July in the south. Leaves are shiny.
