I picked this up at Lowes in the late fall, early winter of 2011 as a small plant and was wondering if anyone here grows this or even seen a mature plant of this type? The first winter I kept it inside but last winter I had it outside where I can keep the soil dry but the temps get cold and it did fine, it has grown good and may be a new plant for tortoise food, but it would be easier if it doesn't get real tall, All I know about it is, it is in the opuntia family. Thanks
