This is a small plant probably only about 6-7" tall. It might be a weed but I never have noticed it before.
The pictures show more than I can tell you. It has come up in a raised cold frame where I grow cuttings. There are like 4-5 of these plants, all the same size and growing fast. I'd like to know if I should grow it or pull it. If you can ID I would appreciate it much. Thanks.
Looks like y'all have solved another mystery for me. The plants are coming up fine in the cold frame so I think I'l let them grow for a while. I can always pull it out later. Thanks again and if in the Spring, it flowers or sets fruit or does something remarkable I'll let you know. For now it is just a happy little Nettle making the best of my cold frame.
