Big, bold blooms cover the plant in midsummer and again in late summer, as this variety blooms on both old and new wood. Even if a late frost kills off your buds, it will still bloom in late summer (great news for northern gardeners!). Large 4-6" bloom heads are pink in alkaline soil, blue in acidic soil, on a compact 3-5' plant. Likes moist but well-drained soil. Zones 5-9. 4" pot. Hydrangea macrophylla 'All Summer Beauty'.
