Amen! It is right up there with purslane, catnip, and dill for reseeding itself.
We have way more come up than we know what to do with; a lot of it gets tilled, just to keep it more less in bounds. We really don’t use much of it; instead, we let it go to seed, as we go through a lot of coriander in our cooking & preserving.
cooked in fried eggs with chopped onions. cooked with hash browns. since I have so much, I pulled some up and shred it around my new plants to try to keep rabbits away. And yes, I have to till around it to give it borders.
