Hydrangea paniculata, or panicled hydrangea, is a species of flowering plant in the family Hydrangeaceae native to southern and eastern China, Korea, Japan and Russia (Sakhalin).[2][3] It was first formally described by Philipp Franz von Siebold in 1829.[4]

Description

It is a deciduous shrub or small tree, 1–5 m (3.3–16.4 ft) tall by 2.5 m (8 ft) broad, growing in sparse forests or thickets in valleys or on mountain slopes.[2]

The leaves are broadly oval, toothed and 7–15 cm (3–6 in) long. In late summer it bears large conical panicles of creamy white fertile flowers, together with pinkish-white sterile florets. Florets may open pale green, grading to white with age, thus creating a pleasing “two-tone” effect.[5]

Cultivation

H. paniculata 'Grandiflora'

In cultivation it is pruned in spring to obtain larger flower heads.[6]

Numerous cultivars have been developed for ornamental use, of which the following have gained the Royal Horticultural Society’s Award of Garden Merit:-[7]

  • ’Big Ben’[8]
  • ’Limelight’ (PBR)[9]
  • ’Phantom’[10]
  • Pink Diamond = ‘Interhydia’[11]
  • Pinky-Winky = ‘Dvppinky’ (PBR)[12]
  • ’Silver Dollar’[13] (suitable for smaller gardens)

Those cultivars marked (PBR) are protected by plant breeders' rights from unauthorised propagation.

Other cultivars include:

  • ‘Praecox,’[14] a particularly early flowering cultivar

Uses

Hydrangea paniculata is sometimes smoked as an intoxicant, despite the danger of illness and/or death due to the cyanide[15][unreliable source?] present as cyanogenic glycosides.[16]

Etymology

Hydrangea is derived from Greek, meaning ‘water vessel’, in reference to the shape of the capsules.[17]

Paniculata means ‘with branched-racemose or cymose inflorescences’, ‘tufted’, ‘paniculate’, or ‘with panicles’. This name is about the flowers of this species.[17]
