Red Russian has survived the last few winters in upstate New York (Draw a
line due west of Boston (the American one), and north from New York city;
I'm just about at the intersection). Even flowered and set seed the next
year, despite being eaten to the ground by local wildlife. Tuscan Kale AKA
Dinosaur and a few others didn't. I've got a dozen plants in the root
cellar, hoping to plant them out in the spring for seed. I hope it works;
I like that one a lot!
