Usually this goes the other way around, right!? I'm raising my first mint plant and it seems to have an intruder. These random sprouts came up after 3 weeks of owning the plant. The day I brought it home I transplanted it into a brand new pot. Regular watering. It sits on the window sill indoors 24/7. But it is directly under a Dracaena.

From researching I think it's some sort of leafy grass? It's a single-leaf alternating growth.

What is it and should I try to pull the new shoots up as they come? How do I eradicate it? I'm worried my mint will crowd itSELF out soon enough, I don't want another random grass/weed vying for space! Thanks for looking. :)
