Three years ago I bought a tiny acer from outside acut price shop. It is now two feet six tall , it is throwing off long fronds which are protruding about about two feet beyond the the rest of the branches. The acer is green with deep cut leaves. There wasn't a label with it so Idont know its name . I have never come across anything like this before . Is this a mutation. Could it be a weeping acer . Help please.
