Coming up in my garden right next to some forest (primarily oak mixed with beech, birch, maple) in southwest Sweden. Last year i dug the area out and removed (most) roots. Not much came up but this little sprout. I suppose it could be roots reaching in from the adjacent forest.
Looks like Griffith's spurge, leaves don't look as sharp though, perhaps it's some other Euphorbia. Doesn't look thick enough to be Asparagus, I'm no expert though
Yea doesn’t look quite right. Japanese knotweed is another similar one, but I’ve never had it here either. Its also still very early in the spring, nighttime is 2-4c so most plants are still dormant. So I don’t think its anything exotic.
