Mary Jane,
Why don't you leave them outside in the garden. The stolons you saw are
normal for A. concinnum and each one will give a new tuber next spring if
left undisturbed. If you cut them, you will probably get no growth. Many
tuberlets severed before having their own roots never produce any shoot.
If your garden is not too cold - in mine temperature drops to - 15=B0C =- A.
concinnum is perfectly hardy in not too damp conditions.
