Characteristics
Description
Lacecap Hydrangea is a deciduous shrub from the Hydrangeaceae family native to Japan, growing wild in coastal areas of the Izu Peninsula, Boso Peninsula, Aichi, Wakayama, and Kochi. Named for its decorative flowers that open only around the periphery, resembling a picture frame. The contrast between the small bisexual flowers in the center and the decorative flowers around the edge is beautiful, with flower colors changing according to soil pH. It is the original species of common hydrangea (Hortensias), with garden varieties having more vivid colors or double decorative flowers.
