Lari Ann, Will this survive going dormant for the winter or will I need to keep it growing. Space is short here but I really don't want to lose this one - it's starting to size up a bit.

Thanks

Where are you located? I usually prefer to err on the side of caution, meaning that I would try to protect the plant a little more than might be warranted by my zone. So even if folks have reported your plant surviving over winter in the ground, if it has sized up nicely, I'd still think about how I could protect it even more.

Sorry about forgetting the zone. It's in a pot and needs to come inside for zone 5 winters, so the issue is keeping it going in a bright window or letting it go dormant in the pot in the basement.

If you can manage it, the best approach (IMHO) is to keep the plant growing during your winter. This way, you won't risk losing it while dormant, and you'll have a great start come Spring. My take on Colocasias is that they prefer wet feet and so drying them out to force dormancy is probably not the best way to treat them.

Thank you. That is what I did last winter and they have sized up a great bit from then. Can you tell me how big this one will eventually get?

I think it will depend largely on the care it receives. Well-grown cultivated specimens can become much larger than ones naturalized or growing in habitat. So that is part of the fun of growing these plants (to me). You may get to see how large they really can grow! I'm thinking 4 to 5 feet or more, but I'm going by my experience with Alocasias which are not the same.
