Blaumeise is considered by many to be one of the best of the Lacecap Hydrangeas producing very large flower clusters that are surrounded by some of the most deeply colored and themselves very large, showy sterile florets. In acidic soils the flowers are a deep royal blue and in alkaline soils the flowers are a dark rosy red. The foliage is large and shiny and is held on stout sturdy stems. The only drawback for this amazing Hydrangea cultivar is that it has limited cold hardiness and is will probably be best grown in zones 8 and warmer. An eastern or partially shaded southern exposure might be optimum even then. Item# 10731.
