Because I’m in an area with no Spanish slugs (yet) which terrorise most gardens, i have never brought in any organic matter. Nor is it very common to grow bamboo in Sweden afaik.
I’m so confident its Not bamboo I will disregard the previous advice to rip it out so we can find out.

I'll second this. It grows in early spring, the stem will "split" into two large leaves and a stem with white little bell-like flowers, and later red berries.

Very common in the entirety of Sweden iirc, my mom used to pick a small bouquet every spring which she would put in a glass of water.

It's very pretty and smells wonderful, but the entire plant is poisonous so be sure to wash your hands after touching it.

Theres never been bamboo around here afaik, nor have i brought any plants or soils in from elsewhere.
I really doubt it is bamboo but thanks for the guess!

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.

Never seen sugar cane growing in Sweden. Never had that or bamboo here so i doubt it is either. Perhaps there are relatives native to my area. But thanks for sharing your guess!

Very much doubt it, its not really something that grows around here. Good guess tho the sprouts look quite similar!

The spot used to be a gravel patch overgrown by forest offshoots, mostly maple root sprouts, which I cut down early spring last year, cardboarded and covered. This is on the very edge which is why i suspected a root growth or something creeeping in. Most guesses so far have been rhizomal species, which all appear to have similar asparagus looking sprouts. The lily sprout looks similar too but there’s multiple differences, thus i don’t think this is it. Thanks for guessing!

Yea i tried PlantNet too but theres not enough plant to ID. It just keeps suggesting ginger.

Glyphosates have no place in nature. Id rather my whole farm overrun by bamboo before i poison it. Besides, there is no bamboo anywhere in my area and i haven’t brought in any organic materials from elsewhere.
