Now that you mention it, I believe I did inquire about cut roses through Garden Valley a few years ago. Local wholesalers started carrying garden Roses soon after, and has been my source since.
Apparently, this area is bad for RR virus. I've been noticing commercial plantings of Knockouts that are plagued with it. I'm really tired of seeing Knockout everywhere as they've become the Stella D'oro of the Rose world to my eyes, but didn't want to see them go out like that! LOL
