I found this in the middle of winter under a snow pile. The roots were not buried, the entire plant was above ground. The leaves were were still green and looked healthy as it does today. I decided to put it in a pot. Spring came I put it on my deck. Barely ever gave it water. It grew very slowly. As the summer heat go worse I decided to give it water, and it just grew and grew. I have no idea what it is. The leaves feel rubbery and edges are spiky.
