From Dirr's Manual of Woody Landscape Plants:

"Bright green, lush foliage, numerous white panicles....."

strange how he contradicts himself witht the foliage color... my Kyushu has bright green foliage but it's quite young, maybe they darken in shade...

New in my garden in 2004. A little desapointed I was expecting a nice pink color in fall as many hydrangea paniculata, but not this cultivar unfortunately.

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):

Medium sized with thin but firm branches. The leaves are shiny dark green, making the plant easy to identify even without flowers. Fertile flowers are white to greenish white, ray flowers relatively few and the sepals are small. Van Gelderen states, "It is one of the most popular cultivars", but Dirr states that his "overall landscape impression is minimally enthusiastic." Flowers in July.
