Thank you, Alberto and Alberto. I'll keep my plant dry during the winter, but I will give it a little water from time to time. The plant is fairly small (in a three inch pot) but it does behave as a caudiciform with about an inch of tuber above soil level. I. platensis is also known as I. platense (as Leo Martin indicated.) The only other name I found was I. digitata v. septempartita. It is native to parts of Argentina, Uruguay, and Paraguay, and apparently takes its name from the Rio de la Plata.

It is now 12 year old, a really big tuberous root emerging from the ground ( I grow it in pot). In winter I cut the vegetation and leave the pot (clay pot) almost dry in a min. +10 room. I put once a month a little water from the bottom. In spring when I see the sprouting gems I begin to water freely. > Alberto > Italy
