Kale is a staple here at Goldbush Micro Farm, we grow three different varieties of Kale, Curly kale, Tuscan kale and Red Russian kale. They are interchangeable in recipes but they do shine brighter for some specific uses. Check out the kale info sheet on more info on ALL the kales plus five fantastic kale recipes.
By the way, the baby kale we grow and sell in compostable bags is the Red Russian kale and can also be used anywhere you would use larger bunched kale, except I wouldn't recommend it for kale chips.
