Emerald Arch features lustrous arching green leaves to 50cm tall and wide. Beautiful blue, lily-like flowers from September to November. Prefers dappled to full shade and is drought and frost tolerant. Good drainage is important - dig in clay breaker and compost to existing soil.
Suits mass plantings under trees, in shady courtyards and atriums. Excellent if you want to create a tropical feel with a very cold hardy plant.
