A-Z of Plants
Zantedeschia aethiopica is also known as Calla Lily or Arum Lily. These perennials can be deciduous or semi-evergreen and are native to Southern Africa.
Zantedeschia aethiopica 'Crowborough' produces beautiful white flowers from late spring into summer and will sometimes bloom again in autumn if regularly deadheaded. The exotic looking flowers sit on top of a clump of arrow-shaped, dark green, waxy leaves.
These perennials look fantastic when grown beside water or as a margin for a pathway. They prefer moist soil and will thrive in mud or natural ponds. They can be planted in aquatic compost and grown in water up to 30cm deep. They need full sun and will grow to an ultimate height of approximately 1 metre.
As Calla Lilies are used to a hot climate they will need some form of protection in winter in a frost-free environment.
All parts of the plant are very poisonous and can cause serious illness if eaten. The boiled leaves of Calla lilies are said to have been used in herbalism to cure headaches, though we wouldn't recommend trying it!
