>>296574Here is another image of it from a different angle, hopefully someone can ID this plant! (other image here:

I just looked up a Lambs Quarters image and those leaves are rounded. The leaves on the unknown plant in my yard are somewhat serrated/pointy like a raspberry or blackberry but it doesn't have enough serrations nor does it have a spiny stem or canes so I have no idea what it is or how it got there. The new leaves forming do look light green/brown just like raspberries and blackberries so I'm confused at what it could be. I don't know if I should kill it or dig it out now and save it before the roots get deeper and it would be settled into its position. I want to start a raspberry patch and this would be a welcome addition if infact it is a raspberry that mysteriously came from somewhere.
