Hydrangea paniculata 'Grandiflora'

Hydrangea 'Grandiflora', Panicle Hydrangea 'Grandiflora', Hydrangea 'Pee Gee'


Deservedly popular, Hydrangea paniculata 'Grandiflora' or 'PeeGee' is a large, upright, deciduous shrub or small tree with conical flower panicles, up to 18 in. long (45 cm), packed almost entirely with sterile florets. Showy, the creamy-white florets become pink-tinged as fall approaches. Blooming profusely from midsummer to fall, the charming blossoms are so heavy that the branches bend over with their weight. The foliage of ovate, serrated, dark green leaves shows hints of yellow to reddish-purple in the fall. Introduced from Japan in 1860s, 'Grandiflora' is an excellent subject for the mixed border.

  • This deciduous shrub typically grows up to 10-25 ft. tall (300-750 cm) and 8-15 ft. large (240-450 cm).
  • Sun or partial sun lover, it thrives in rich, medium moisture, well-drained soils and tolerates heat, humidity and urban environment. Afternoon shade in hot summer climates is recommended.
  • Easy-to-grow plant with reliable flowering and flower color regardless of soil PH.
  • Mass in mixed shrub borders for dramatic summer blooms, in front of walls, fences, taller shrubs and trees. Great as an accent plant or hedge too. Panicles may be cut for fresh arrangements or for drying.
  • Best if pruned back in late winter or early spring. Blooms occur on current season's growth, ensuring reliable flowering.
  • Can cause mild stomach upset if ingested and contact with foliage may aggravate skin allergies.
