have had this plant almost a year now. first in a pot in partial sun (slow but steady growth), then planted in the garden in full sun (nearly burned to death) and now back in a pot in filtered sun. suddenly the growth this fall has been crazy good and i finally have my first flower. i water no more than once a week and less now in winter. i do mist under the leaves often for spidermite prevention. don't know where it will end up this summer as it is bound to outgrow the pot at the present rate it's going. all in all, a fascinating plant. the leaves are thick and leathery, yet soft. i love touching it.

I've grown this in the ground, zone 5. It gets very big. In my experience it didn't get any more water than the rest of the garden.
Difficult to transplant, probably doesn't like being moved.

This is a wonderful Zantedeschia aethiopica variant. In a climate where it doesn't freeze back, bloom heights of over 80 inches have been reported.

I grew mine in a water-filled trough and it flourished.

The leaves are leathery and of very heavy substance.
