The perennial kales overwintered well the last two winters and are looking good. I showed a video of one I got from Walsall Allotments in Birmingham, UK a few years ago here last week: https://www.edimentals.com/blog/?p=25787
The first below is one of Chris Homanics’ perennial crosses (I lost track of which cross this is). It has large dark glossy leaves (a bit reminiscent of Glazed collards) and hasn’t flowered, concentrating instead its energy into producing leaves! This is a keeper.
This is followed by non-flowering offspring of my Daubenton cross with Purple Sprouting Broccoli in 2012 and still alive https://www.edimentals.com/blog/?page_id=1632. These have inherited the daubenton genes but one is taller and has bigger leaves. I’m still playing with the offspring on the broccoli side, but they are less perennial but some have survived for 5 years but the broccolis are smaller than the father, but still useful.
Finally is a current picture of Daubenton variegated.
AND Diamond back moth (kålmøll) is now here in large numbers (over 100) and will have almost no impact on these kales, nor will other pests!
