Positive lmelling On Dec 2, 2004, lmelling from Ithaca, NY (Zone 5b) wrote:

According to the authors of "Encyclopedia of Hydrangeas" (2004 - Timber Press)," A large shrub up to 6.5'. The corymbs are flattened and the sepals are large. In its pink or cherry red form, it is a very nice cultivar. In acid soil, it becomes mauve, or brick red. Synonyms: 'Glory of Aalsmeer' (bred by D. Baardse, Netherlands, in 1930), 'Aalsmeer's Glory'. Very similar to 'Hobergine', which was introduced by Hofstede. Introduced by F. Matthes, Germany, in 1929 and probably renamed by Baardse in 1930."

No zone hardiness given.

Other notes: fringed, free-flowering; mid-season. Has a "frilly" look. Cold sensitive.
