I have a maple tree in my backyard that is a dark purplish all year. Growing up we called it the Black maple, but I have looked at pictures of Black maples and seen green leaves. Then I thought maybe it is called a Cherry maple, but a quick web search proved that wrong. I thought then is it a Red maple, but those appear to only be red with new growth and fall. So what maple tree is dark purple all year long? Please help me.
