I found this plant on the street thrown out, was very sad looking, but after a haircut its growing so nicely and really fast! Can anybody tell me what is it? I first thought it was aloe vera, but when I cut the bottom leaves there was no juice in them. Is it possible that it just hasnt produced the juice yet or is it a different plant? The leaves have little brownish-reddish spikes along the edges.
