Redbor Kale (F1 Hybrid 55 Days)

$ 3.95

The Redbor Kale has been difficult to find for the past couple of years. It was one of our favorites, so we had to bring it back. The color of the mature leaves are unlike any other kale we offer. Harvest often, regrowth is strong after each cutting. Redbor Kale grows well into late fall when cooler temperatures sweeten the flavor and intensify the leaf color to a rich plum. Capture the beauty of it in your garden or container. Ready for harvest in just 7 weeks.
