OBSIDIAN COLLECTION • Uniquely, these hydrangeas have black stems that contrast dramatically with its green foliage and colourful flowers. 'White Knight' has white mophead blooms, 'Black Lace' is a lacecap type in blue to pink, and 'Storm Cloud' features large mopheads that are deep blue or purple through to deep pink. They reach 1.2m tall x 1.2m wide. ENDLESS SUMMER • Hydrangeas traditionally produce just one bloom per stem each year, but 'Endless Summer' hydrangeas are a breakthrough in breeding. They repeat flower, allowing a flowering season 10-12 weeks longer than usual. Pruning below the spent flowers stimulates new growth and new flowers. 'The Original' is the classic blue or pink mophead, while 'Blushing Bride' is white, maturing to blushing pink. Both grow to about 1mx1m. S
