Yes. I have several plants and some of them have turned all green

Great! Just what I need, another all green alocasia. LOL

Mine was very mottled in colr until I put it in medium-to-deep shade. Then the variegations became more prominent and lighter. I now have very nice variegation.

tsmith, my V. Wentii is in very good shade, and gets ample water. It just isn't variegated any more and it hasn't really grown much at all.

Fernaly, may I suggest fertilizing with a tablespoon of Epsom salts to a gallon of water and a generous sprinkle of a time release fertilizer similar to Osmocote. Also, I don't water mine very often, maybe a good watering once a week. I lost a regular wentii to rot by over watering. So for the variegated Wentii I have watered sparingly and it has thrived. It is strange that different varieties within the same family have different water requirements. Alocasia macrorrhiza requires moderate watering but A. Macro. variegata likes wet feet. Good luck to you.
