Dinosaur Kale. Hearty leaves that are tall and narrow. It retains its firm texture even after cooking. It is slightly sweeter with a more delicate taste.

Winter sowing is basically sowing seeds in the bottom of a milk jug during the winter, setting the milk jugs outside for the winter and leaving them there until the seeds germinate in Spring.
