Tuscan kale

I've grow Tuscan kale before, but this plant doesn't quite fit.  It has the dark green crinkled leaves of dinosaur or Tuscan kale, but it keeps growing.  It's not Jersey kale (walking stick kale) -- I have seeds of that, but the leaves aren't right.

It must just be a robust Tuscan kale plant that has kept growing in this mild spring and early summer.

Happily, the leaves are tough enough to deter the cabbage white butterfly caterpillars, too.
