Fedco has it, they call it Sea Kale. "Winter Hardy Kale" might be
misleading
since most kales are winter hardy. The kale you describe is unique in
that
it is perennial rather than biennial as most kale is. Make sure your seed
source says *perennial* kale. Even that, alas, isn't what it could
be. The
perennial kale lasts a few years. Typically five or six. We reguarly
harvest kale
from the ordinary biennial plants for 18 months or longer and some go the
full two years before going to seed.
mizuna, tsa-tso, corn salad, etc) can be wintered over if the air
temperatures
will stay above 0 degrees F. I've compared notes with several local
gardeners
and we've found that 26 degrees F seems to be the magic number where the
greens
have to be covered to prevent any damage.
The very biggest spinach we've ever had was planted last January in
weather
much like this (also under soda jug cloches). I had hope of winter
spinach but
it grew to about an inch high and stopped. That is, until around the Ides
of
March when it grew into gigantic 18" leaves. *Almost* got our fill of
fresh
spinach that year. Almost.
