Gardeners' Notes:

Negative	gxiong	On Jun 21, 2008, gxiong from Knoxville, TN (Zone 6b) wrote: This shrub does not like extreme heat. Even under shade this plant will wilt. It is unfortunate since this hydrangea is so beautiful; the nearly black stems contrasting with the pink flower clusters make this an unusual addition to any hydrangea lover's garden. I've tried moving this hydrangea at least four times to find the perfect spot for it to thrive. This hydrangea blooms on new wood, so I recommend it for cooler climate zones.
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 huge shrub with slender purplish black branches ( a distinguishing characteristic), sometimes up to 6.5 feet. The flowerheads are untiday, pale pink or lightest blue, sepals entire. Flowering time is from August to September. This interesting plant was forgotten for many years but is again available." AKA 'Cyanoclada', 'Kuro jaku', 'Mandshurica'. Imported from China to the US by E.H.Wilson in 1853. Not cold hardy. Flowers form at terminal buds.
