Hydrangea macrophylla 'Sister Theresa'

A decidous, upright, small shrub with dark green, ovate, serrated foliage and large pure white mop head flowers in the summer until autumn, with each single floret having a small blue eye. In the autumn the flower heads become green tinted with red when they are dry.

Plant Care: Bloom occurs on old wood. Prune any time after flowering by cutting back flowering stems to a pair of healthy buds. Prune out weak or winter-damaged stems in early spring. Mulch young plants with a well-rotted manure or compost in spring. For more information on pruning and care click here
