I'll post these over in the right thread once I know what it is... any ideas?

I dug one up from a rent house yard, and have moved it three times since then. It seems to thrive out on the corner by the stop sign in full sun where we now live, having gone from a little seedling into a small bushy perennial. Dies back over the winter.

The other one volunteered in a pot of alyssum and vinca, and I'll put it in the ground once I empty that pot.
