Does it need shade or sun?
Possibly palm grass, Setaria pulmifolia.
Or maybe a bunch of palm seedlings, like Queen palm.
Where did it come from?
I'll just have to let these grow somemore to figure out which plant this is, Queen palm or setaria pulmifolia. It's not bletilla, I have some of that and it's a bit different.
Is that ONE plant? Or multiple plants? Did you dig it up? Was it given to you? Did you purchase it? Need more information.
