What's this grassy weed?
I just noticed these mixed in with my peonies. They're a little over a foot tall. When I tried to pull one up by the roots, it snapped off with very little pressure. There's a sticky sap that starts out clear but then turns deep purple. I got some on my fingers and it stained my skin.
At the top, you can see a cluster of buds. If I pinch them open, there's more sticky sap and little purple balls. I'll upload a pic of them next.
TIA for any help!
