Tuscan kale is mostly a biannual. That means what you plant this year should take two years to flower. Which in one reason they are a great hungry gap vegetable.

They also take cold temperatures well. And can be harvested all winter. Especially the second year plants.

The main problem in recent years (and oddly only in the past few years has this been an issue for me) is they can be decimated by cabbage butterfly larva. Not a problem in winter, but once Spring and summer warms up, I plan to put this years kale under netting.
