Hydrangea paniculata in varietys

Unlike mophead and lacecap hydrangeas, panicle hydrangeas will flower better if given some direct sun, so they'll enjoy growing in a position of full sun or partial shade, in moist, well-drained, fertile soil. Like Hydrangea arborescens, panicle hydrangeas flower on the current year's growth, so they should be pruned in early spring. You can prune the hydrangeas earlier but the faded flowerheads look beautiful over winter. Cut back old stems to leave around four pairs of buds on the stem. This will encourage vigorous new growth that will bear the largest panicles.
