What the heck is this plant?
Hoping you can help me figure out what this plant is. I'm a new gardener, planted a bunch of things but forgot to label them, and now I have a few of these odd things in my container garden.
They have what look like mini-thorns on the outside, but they don't sting. Pretty big plants compared to everything else. And they just shot up within a few weeks.
Some things that are within the realm of possibility:
Early snowball turnip
It's probably not a weed, since I started the garden from scratch using potting mix. I live in Toronto. Any thoughts would be helpful.
