Information from both "Hydrangeas for American Gardens," by Michael A. Dirr (2004) and "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press).

Conflicts arise between the two texts as to exact size, one claiming it grows to 3.5 feet, the other saying it grows 4' to 6' tall. This is a free- flowering shrub with dark pink to a vivid deep blue flower, with serrate sepals. Leaves are also serrate and are dark green. Stems are heavily spotted or stained purple-black.. Flowers last for 4 to 5 months; red, blue, and green sepaled during the autumn. Great for drying.
Should be hardy to zone 6.
