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.
It's a flower of some sort and certainly not bamboo. I've seen shoots like that quite a few times, but couldn't put my finger on what flower it is.
I uploaded the image into a plant identifier and the returns were mostly orchids.
Yea i tried PlantNet too but theres not enough plant to ID. It just keeps suggesting ginger.
