Zantedeschia Crowborough – ‘Arum Lily’ (12 litre Pot)

Unusual, pure white hood-shaped flowers that are up to 10-15cm (4-6in) long are produced from late spring to mid-summer. It makes a striking architectural clump with lovely arrow-shaped, glossy dark green leaves. It looks great grown beside water as a marginal plant and can be left outside in most frost-prone areas if it is given a deep winter mulch.

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
