Dear Bona venutre,
I THINK you are mistaken about what your plants are, there is a Typhonodorum lindleanum, not a Typhonium!   Typhonodorum is a HUGE (grows to about 6' tall, looks like a banana 'tree'!), aquatic aroid from Madagascar and nearby Islands, it MUST be kept wet and warm!   Check w/ Brian Williams, he distributed seed of this about a year ago.   I believe Brian has heaters even in the water, as the roots suffer greatly in winter when the water gets cool.   The larger plants develop a 'knot'-like structure at the plant`s base, but I would not call it a tuber, and it does not go dormant!   There is a great article on growing this wonderful giant aroid in Australia in a back-issue of Aroideana (get your back-issues while they last!).
Good luck,
>>My 4 plantlets of T. lindleyanum grew a few extra inches/a few leaves this spring and summer, up to 9 inches tall. The 2 in pots sitting in trays of water did better than the 2 in ground. Now we are getting occasional nights down to 50F here in New Jersey. My question is, will they go dormant just like Typhonium venosum, should I start drying them out now. If not, how long can they be left outdoors here. Will they be damaged (root-wise) by a touch of frost? What kind of tuber or rhizome do they have? I can bring them in and dry them out now, or keep them going under lights as they seem to want to be making more new leaves.
Please advise us who have received these plantlets.
