Just from the name alone, I think I would prefer “lacecap” and where Hydrangeas are concerned I prefer the more open lacecap flowers to the large pom poms of the mopheads. When my mother came to live with us she brought quite a few mophead varieties with her which she had grown in pots- these were liberated into the garden where they responded by forming huge plants. They started off pink but now most of them have turned blue with just a couple staying their original colour.
Most of the hydrangeas that I have bought have been of the lacecap variety or cones – Hydrangea paniculata- which somehow seem more delicate, even though they are now quite sizable bushes
Hydrangeas are so dependable for colour throughout summer and into autumn and so useful for flower arranging – where would we be without them?
