I'm looking for seeds of Rose of Sharon also known as Hibiscus Syriacus. The hardier and the bluer the better. I used to overwinter a 'Blue Bird', but eventually the cold did it in. It was out of zone, but I was fortunate to overwinter it for several years. I Would like seeds of a 'Blue Satin' if they come true.

Am willing to trade for commercial grade seeds of Penstemon grandiflorus (large flowered penstemon).
