Too bad you can't send us a cutting.
I have (or had!) this beautiful mild tasting soft leaved blue green kale that overwintered here and made delicious "mockoli" the following spring. Seeds getting old so I sowed it this year expecting to get some good plants to overwinter. Sadly they've been completely skeletonized by cabbage butterfly while I wasn't paying attention.
Still a chance they will produce new leaves once the butterfly season is kaput. I should look into a rescue op today.
There is much to be said for brassicas with the best leaf quality for salads. Stronger tasting and/or pricklier types are many and productive, but they work better in small amounts for my salad taste. Even Red Russian kale, I find the leaves are too soft to stand up well in salad....
I did get some mizuna seeds this year, it's one of my favorites too.
