Found:

Japanese cultivar, introduced in England 1881

Size:

7 ft

Flower:

Lacecap, sterile flowers are pointed in regular groups of three

Notes:

"Dark green foliage and exquisite, delicate lacecaps of large, white, sterile florets (fading to chartreuse as the season progresses) surrounding blue, fertile flowers, make this one of the most popular Hydrangeas in the garden when in full blossom. A sturdy performer in a fairly shaded bed in our woodland, it would perhaps be better grown if planted in brighter conditions than we currently provide. 6 ft."
