Is this a begonia? A lady having a garage sale was kind enough to share a slip of it with me and now I don't know what to do with it? I've got it in water but I don't know if the black things are roots (never seen any like it) Should I put it in dirt or let it get more roots? Will one of the stems root if I cut it off the main tuber if that's what it is. Sorry but I don't have a clue!! I'll post another pic dont' know how to post more than one.Thanks.
