This hydrangea has the most beautiful deep pink color. I have 7 different hydrangea cultivars in my yard and this is my favorite. It glows in the shade. I will have to figure out how to add a photo because the one here obviously isn't flattering. Highly recommended.

From the "Encyclopedia of Hydrangeas," (Van Gelderen -2004)," A vigorous growing shrub up to 5'. Corymbs large, 8'-9' across, sepals equally large, heart shaped, soft pink or pale blue. The plant needs some protection in a harsh winter. According to Haworth-Booth, it is suitable for seaside plantings. Bred by F. Matthes, Germany, in 1923."

No hardiness zone listed.

From "Hydrangeas for American Gardens" by Michael A. Dirr: One of the finest for seaside gardens; not particularly cold hardy." Deep pink in alkaline soil, purplish-blue, french blue, royal blue in acid soils. Flowers have serrated sepals. Free flowering, good for drying, blooms mid-season.
