Hi jmillerent! Where are you located at? I had a B. Sanguinea for years but lost it
last winter and am too looking for seeds. I did get some last spring from an ebayer and they turned out to be D. discolor. So be warned there are some folks out there that well aren't truthful. Know your grower is the key. With the hotter weather we are having it's a crap shoot on growing them. They truely need a cooler climate than what we had this year.
We too are in the PNW in the SW WA area. Our gardens are open until the 15th of Sept by appointment only. After that time we start putting our collection away in their own greenhouse, we call it the Brug house. Scream at me by posting or treemail.
