Sold in 9cm pots.
Similar to Z. 'Hercules', but this variety does not produce spots on its leaves, and is reputed to grow taller (5-8ft at maturity, and in ideal conditions). Leaves are large and leathery and have a slightly grey/glaucous tinge to their leaves. Large white flowers are produced from summer onwards.
Care requirements: plant in free-draining soil in full sun or partial shade. If growing in shade then it is less likely to flower, but will produce larger leaves. Appreciates copious amounts of water during the summer. Well-suited to growing in pots or as a pond marginal. Deadhead flowers when they die back.
