If you want to give a surprise factor in your home, pick a hydrangea color that is in contrast to your home and place them in a large vase. This would make your visitors immediately focus on the arrangement and sooth their souls.
Pruning Hydrangeas Most hydrangea types -- pink, blue, or white mopheads and lacecaps, or oakleaf forms -- bloom on old wood. Prune these types of hydrangeas before midsummer. If you prune them in winter or early spring, you'll be removing flower buds.
