Positive	woodsplantlady	On Jul 17, 2009, woodsplantlady from Chesterton, IN wrote: I grow this fantastic plant in zone 5 on the south side of the house. It is huge and its flower clusters exceed the oft-cited 8 inches. Regularly wins the blue ribbon for blue hydrangeas at the county fair.
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 large shrub up to 6.5', possibly more. The foliage is almost orbicular. The flowerheads are large, about 8" across, light pink or light blue, sepals entire. Flowering time is from July to August. Very free flowering. The autumn color of the sepals is white with red dots. Origin Japanese." Other information: vigorous grower, glossy light green foliage. Flowers good for drying. No hardiness zone noted.
