The first picture shows the 'Blue Scotch' kale (on the left) that had overwintered twice and a single offspring of it from pollen of an ornamental dark purple "flowering cabbage". The hybrid was really vigorous but didn't express much purple. Luckily it was carrying all of the necessary genes and has passed them on to its descendents.
The second picture shows three seedlings of 'Green Glaze' collard greens. This old obscure variety was the source of the glossy trait in my current lines. The seedling on the left was from a cross with pollen of 'Blue Scotch' kale. The center seedling appears to be a selfing. The one on the right is from pollen of that same ornamental dark purple "flowering cabbage".
