What are they? Have a heck of a smell.

We have some of these here, they grow in the ironore and Rocky soil.
According to this it's frost weed. (Have at it Norml )

Looks kinda like bitter weed to me. Toxic to sheep and goats.

Weed, but a pretty weed, kill it.

I'm not familiar with that one....

It has a very powerful smell. More like a bush than a weed.

It’s either a weed or a flower. Depends on whether you want it or not.

I’m going with bitterweed

Looks like the bitter we have here (Deep East Texas) but I'd like to see a clearer pic and close up of the flower first. Bitterweed has a large bulbous center in the flower.

I've managed to get it all of my pastures or I'd post a photo.
