| Positive | On Aug 18, 2011, fel from Wynnewood, PA (Zone 7a) wrote: The blooms on this plant are marginal in my zone 6b/7a. It blooms on old wood only. The 7 year old plant in my front garden dies back each winter, and then grows to a small shrub again, but never blooms (even with protection). Divisions that I replanted in my backyard bloom each year, even without protection. The blooms are gorgeous, and the plant seems more drought tolerant than other hydrangeas I have. |
| Neutral | On Dec 2, 2004, lmelling from Ithaca, NY (Zone 5b) wrote: According to the authors of "Encyclopedia of Hydrangeas" (2004 - Timber Press), "A strong growing shrub with many thin, but firm branches. The flowers are remarkably bicolored, the sepals are red with white margins. The whole plant looks somewhat untidy, but is interesting for its unique flowers. Synonyms: 'Bicolor', 'Sensation 75' . Sometimes misspelled as 'Harlekijn'. Bred by August Steiniger, Germany, in 1957. |
