We may not be thrilled with all this rain, but the hydrangeas are loving it. Right now the Pee Gee hydrangeas — or Hydrangea paniculata ‘Grandiflora’ — are taking center stage.
The Pee Gee hydrangea grows to a height of 10–20′ and a spread of 10–20′ at maturity. Full sun and partial shade are best for this shrub, meaning it prefers a minimum of 4 hours of direct, unfiltered sunlight each day.
The Pee Gees are tolerant of most soils and hardy in zones 3-8. They bloom on new wood, so pruning should be done in late winter to early spring before growth has resumed. This helps promote bloom and maintain size, but if you don’t get around to pruning, you will still get a great show. A Pee Gee can also be pruned into a small tree.
The word ‘hydrangea’ is derived from the Greek, meaning ‘water vessel’, in reference to the shape of the seed capsules. ‘Paniculata’ refers to the loose-branching flower form. ‘Grandiflora’ needs no explaining.
