Kayte and Rob were trying to help me identify the plant that I clipped off a piece of with seed pods on it and brought to the swap at Gordon's this afternoon. I wanted to post some pics of it as it was growing before turning in for the night, to see if anyone on the PacNW forum might have seen this around their yard and know what it is. I put it up on the ID forum and the closest suggestion was Hesperis matronalis, but I'm just not positive that that's what it is. The plant's height right now is approx. 18 inches or so I'd say. Popped up in bare dirt after building our garage in the backyard.
