Hydrangea paniculata 'GRANDIFLORA'

Grandiflora is a panicle type hydrangea, not a mop-head one with big leaves and large flower heads. It has 20-30 cm long panicles with mostly sterile (= showy) flowers giving the inflorescence full and rich appearance. The flowers come out in the second half of summer. They are white at first, changing to pink in early autumn. Deciduous leaves are ovate, deep green.

Flowers are ideal for cutting – they last a long time cut fresh when white, or they can be cut when they have turned pink, and dried. The shrub grows fast, especially after spring pruning which is ideal if you want to have a dense and well-behaved plant. Cut back last year´s growths to about a third every spring before buds begin to swell.

It will grow in almost any soil type, preferably humus-rich, moist soil that will not too heavy or shallow. You can plant it in sun or shade, it can take both, but loves plenty of sun for profuse flowering. Hardy to about -34°C (USDA zone 4).
