Panicle hydrangeas are Hydrangea paniculata and its cultivars, all of which are characterised by their large, almost pyramidal flowerheads, or panicles.


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.

Panicle hydrangea flower colour

Unlike mophead and lacecap hydrangeas, which have interchangeable flower colours (pink in alkaline soil, blue in acid soil), panicle hydrangeas are much less affected by soil pH – the flowers nearly always turn various shades of pink as they mature.

Tree-form hydrangeas

Panicle hydrangeas are most often grown as bushy border shrubs, or in a row to create an informal hedge. If you're after a different look, panicle hydrangeas can be bought as, or pruned and trained to form multi-stemmed, tree-form specimens offering extra height and a visible branching structure to be admired.
