Any more detail possible other than macrophylla lacecap? I thought because of the leaf detail it may be possible.
Looks like my Mariesii except my blooms were blue because of the acidic soil its in.
Light-O-Day Hydrangea, a mutation from the Endless Summer Hydrangea, also has lace cap type flowers (blue/Pink). The introducer, Bailey Nursery, got apprehensive about the performance of this variety and repotted it from blue pots to black; renamed it from Eclipse to Light O Day.
