personally i wouldnt plant it out now. as for slugs then welcome to the war! lots of remedies for keeping them under control.

Agree - admire it inside instead.

And dont forget the dreaded red lily beetle ,even tho mine are dying back at the moment they still keep appearing ;).

Thanks everyone, are lilies any good in pots?

Lily Beetles don't attack Zantedeschias--thank goodness! Also, only Z. aethiopica 'Crowborough' is hardy enough to plant out in the garden in the UK. Zantedeschias are excellent in pots, though. The one you have likes very bright light, maybe even some morning sun, enough time between soakings to let the top cm of soil to dry, and regular feeding with a good houseplant food while the leaves are present. It goes dormant in the winter, and should be stored cool--but not freezing--and semi-dry--30% humidity.

great thanks
