Zantedeschia aethiopica
Hercules/White Giant
(Giant Arum Lily)

There is slight confusion with this variety as it is quite similar to Zantedeschia White Giant, the variety we have is Zantedeschia Hercules and this variety has spots on the leaves, White Giant has green leaves with no spots.
This perennial is a large growing variety and produces tall white arum Lily flowers with a through summer.
This variety is not widely available in the UK and we have propagated these here in our nursery based in Somerset, South West United Kingdom. This Zantedeschia can grow to a huge size if it is in the correct conditions, with plenty of feed, warmth and moisture it can grow as large as 6ft in a season once established.
A wonderful perennial best in a sheltered position with a loamy soil, sometimes the leaves are frost damaged during winter, if this happens after the last frosts trim back the foliage and new shoots will appear from below the ground.

Hardy but protect from extreme conditions

Supplied in either a 9cm pot or 2 Litre pot, please select from the drop down menu when ordering.
 
The hardy forms of Zantedeschia are varieties that derive from the species Zantedeschia  aethiopica and Zantedeschia pentlandii, these are mainly white flowered varieties sometimes having coloured throats like Zantedeschia aethiopica Kiwi Blush. Zantedeschia pentlandii is striking in having bright yellow flowers.
All the Zantedeschia we grow here are the hardy forms. To ensure these plants thrive in your garden it is best to plant them in moist soil in semi-shade, bright sun can slow their growth and scorch the leaves. Also in mild winters these perennials can be evergreen and put on growth through winter, in this scenario a sharp frost will kill these fresh shoots of the top growth but will not harm the plant, it will just re-shoot from the root in spring. A good mulch over winter greatly helps the plant too by insulating the shoots just below the soil from frost and ensuring a good strong root base from which masses of shoots will appear in the spring.
These plants can also be grown in containers and for this they will respond best to a loam based compost, they don't want to be planted too deep and respond well to regular feeding. When grown in pots the plants should be protected over winter as the root is above the ground (in the pot) and can be damaged by frost. The containers should be watered regularly and the compost should be kept moist at all times. These plants grow well in the UK, we have them here on our nursery in the South West of England but with a bit of protection (fleece in extreme conditions, mulch or moving containers into a greenhouse) they can be grown all over the UK.
