Okay, now it's flowering. Before this thing sets seed, is is something I planted, ya think? I'm still stumped, even seeing the blooms! The leaves are nothing like the garlic mustard that's growing everywhere in our yard at least.
Just a guess, it looks like a vegetable or herb, that has gone to seed!!!!!!!! man, it's somewhat on the tip of my tongue???? Elaine...one of the chards..this happened to one of my chards in a 1/2 oak barrel????
I believe I will yank it, or at least deadhead it before it can set seed. I don't remember planting anything at the base of the birdbath. All sorts of weeds and grass have overtaken this lasagna flowerbed because we (1) didn't first kill the grass (2) didn't put down enough layers of newspaper and (3) didn't put down enough compost and whatnot before mulching. Grrrrrrrr.
GW would you be so kind as to take a pic when flowers open a little more please, I'd like to see if the flower stems elongate and what for the flower heads eventually take. In my mind this is of the Brassicaceae and I've a few possibles but I'm not confident that any match your plant exactly.
Hmmmm...Haven't rubbed it. I will try and remember to get another picture of the flowers tomorrow, provided they're fully blooming at this point. I sure didn't plant any basil there, and the only basil I have in the yard already is purple basil. Hmmmm...Could be a volunteer I guess!
More soon; stay tuned. Same bat-time, same bat-forum.
He wasn't all deep-rooted, so he came up without a fight
I dropped him in the dumpster and put the lid on tight
Tomorrow he will travel far, out to the dump's domain
And mixed in with the refuse there he'll surely sprout again
