Excellent news! The small sutherland kale I suspected was a rooting from the bigger one has been transplanted to the food forest, grown happily, and even survived the winter!
I covered it with a plastic barrel greenhouse though; and the winter was exceedingly mild. I wouldn’t say this kale has proven itself ‘hardy’ yet.
Unfortunate news is it’s sending up flower shoots -profusely. Considering its supposed clone-parent hardly gave a flower, I doubt it really is a clone and is more likely a seedling -an especially stocky seedling.
Even biennial kales can have their life extended by prohibiting seeding. I harvested the shoots along with the asparagus spears pictured and some early turkish rocket buds and cooked them up for a very tasty lunch.
