Just a quick question - any chance Mountain Maple (Acer spicatum) is good for bonsai? I have a number of them growing on my property. I thought they were Striped Maples (no good for bonsai, apparently) until they started to flower. I'm guessing they probably aren't very good for bonsai but thought it was worth asking. It's difficult to find info because Japanese maples are sometimes called mountain maples, too.
