ILPARW (southeast Pennsylvania - Zone 6b) on Jul 6, 2019 2:36 PM concerning plant:
This Hills of Snow Hydrangea is the old-fashioned hortensia or mophead cultivar of the Smooth Hydrangea that has rounded flower clusters of almost all showy, infertile florets. The flower heads are about 6 to 8 inches across with very few or no fertile florets for any pollinators. I don't see this once very popular cultivar very much anymore in the Midwest or Mid-Atlantic USA as it has been replaced by the very popular cultivar of 'Annabelle' that has larger, more symmetrical clusters around 12 inches across. I still have a copy of the old Countryside Book called "Home Landscaping" from 1984, mostly unchanged since the 1960's, that has a photo of this plant on page 60. This best selling book of full color plant photos was one book I used in my old landscape design class in the early 1970's to see what plants looked like.
