Yes, I thought it looked familiar. I had it at another place we lived. I didn't remember to take seed. You wouldn't have any extra seed would you? They are such awesome plants. Is yours called Celadine Poppy?
I never thought of using Bleeding Heart in a rock wall, I love that. Now on to putting some in my wall, along with columbine. I have a whole milk jug of mixed columbine I Winter Sowed. First year to do that and I am so impressed with how easy and well it works. Going to do much more next winter.
