I Purchased this plant from Crug farm plants in Wales uk, spring 2007.
So far ever time it grows a new leaf another one dies. It has been hard work!
Its a small plant so at the moment looks the same as most other Alocasia.

April 2008..its growing stronger now and has overwintered ok in my House. I will move him into the greenhouse in may and the into the garden for the summer.
Has produced so many runners that snap off and then you plant them which ever way up you like they still seem to grow.
