Warning: Only true plant geeks are going to appreciate this. I just stumbled upon a great website from Germany with an extensive list of hardy exotic plants. It's called the Internet Portal for Winter Hardy Exotics. The vast majority of these plants are hardy to approximately zone 7b (5 to 10F or -15 to -12C).
Can we really grow this in the PNW?

Never tried but it might be hardy to around 10F/-12C.
