Most hydrangeas grown in British gardens have glossy dark green leaves and large flower-heads. Hydrangea aspera subsp. sargentiana, however, has dull green leaves with bristly hairs on top and a grey down underneath. Its huge flowers appear from late summer to mid-autumn. The inner flowers on the head are small and blue to deep purple, whereas the outer petals are larger and white, occasionally flushed with deep pink.
For best results grow Hydrangea aspera subsp. sargentiana in moist but well-drained soil in full sun to partial shade. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
