Rosie asked and I too have a mystery plant
Mine reminds me of a small Maple tree for some reason. It has white flowers in the spring and now beautiful red berries. Nothing around here seems to be eating the berries. It is not invasive in my landscape. I have moved them from deeper in the forest into my border because they are very pleasant to look at. This seems to be helping them go from one foot to about two in height. I have looked at all the pictures offered in rosie99 question and none of them are what I have. Any ideas what it could be here in MN? My description of my plant would be similar to rosie99. My leaves resemble a maple in forum.
