I live in wisconsin, and i have a tree that now has ripening fruit on it. it resembles a black berry, light, sweet flavor. the tree is maybe 20 ft tall, and the berries are a light red and ripen to black. a little green stem comes off with the berry. i have seen this berry even as a child, some called it a boysenberry, but those are on bushes. what kind of berry grows on trees?
Can't tell decisively from that angle which one you have, though. Mulberry species are not the easiest to tell apart, and certainly not from one photo. If you can include some additional shots that show the tops and bottoms of leaves, some images of the young branches and buds, and a picture of the whole tree - that would help.
The North American native mulberry is Morus rubra, red mulberry.
The Asian species Morus alba (Asian or white mulberry) is also possible, and is widely considered an invasive pest plant.
Both have tasty edible fruits.
VV, wouldn't Morus rubra lack the glossy foliage shown in this photo?
I would be confident to say that I have never seen a Morus alba without glossy foliage, but I would not commit to saying that Morus rubra cannot have glossy foliage. Less likely, perhaps, which makes one lean toward the Asian mulberry but want definitive information.
Where's that tactile function key?
You can only put one picture per post here, but you can keep replying to your thread and add another one each time.
Back off the zoom a bit; you can have more than one leaf in a picture. Yours are incredibly clear by the way; blinding me a bit, and maybe fooling us into a wrong ID.
The leaves look like they have a bit of "heft" and thicker texture to them, than I would ascribe to Asian mulberry. Maybe it is just good tough Wisconsin invasive stock or something on that plant, but the Asian mulberry foliage around here is usually pretty thin stuff.
If you can go out and feel this foliage, tell us if there is any roughness to it at all (top and/or bottom). Asian mulberry will be pretty smooth overall, and red mulberry will have hairiness and thus a rougher feel.
Can you tell that I really want skar to have a keeper...
Morus alba for me too. Not pure M. rubra, but hybrids M. alba × M. rubra exist (e.g. the cultivar 'Illinois Everbearing'), and I guess can't be ruled out.
I also have a Mulberry tree (don't know variety). I have to ask a dumb question. Why do you say red or white if they both have black berries? Mine the leaves are not shine and they are rather thin not thick.
This was my question but it isn't a Mulberry tree. The berry has a single seed and is about the size of a small pea or pencil eraser. Oval in shape and very dark purple almost black to the eye. They are starting to fall from the tree and the deer love them. In the past I have sqeezed one and tasted the juice they are very sweet. I will try to get a picture posted.
It would probably be best if you started a new thread with your ID question, so that more people will be likely to observe it and assist in answering.
