Serena Dark Horse is on my list to get. Love the color.
Techny Spider (Reckamp-Klehm, 1987) is a favorite also. I bought a bunch of these last spring. I didn't get them planted in the ground, so they're still potted in the unheated greenhouse. I'm going to have to shovel my way out there to see what's going on. We're supposed to get a foot of snow today. YUCK!
