Great article!

I have tons, so need no seeds, but the majority of mine are either self-sown or from naturally occurring tip layering.

Our original plant was either bird- or mouse-sown, and came up from under our covered front porch, so they are resilient indeed, and quite determined. ;-)

Fabulous raspberries, great flavor and resilience, and well worth growing.

I should note that I'm on the Highland Ridge of the Cumberland Plateau, in the foothills of the Appalachians, and not the PNW.
