Red Ursa Kale is a hybrid of the two most well-known varieties of kale in the United States: Siberian and Red Russian Kale. Thus, its leaves are wide, fluffy, and ruffled, similar to Siberian Kale. It also has a strong, dusky-green color, with magenta veins and stalks, similar to the Red Russian. They are best to harvest and consume while they’re young, which is when they’re less than six inches long. And although kale started since the Middle Ages, this variety is a relatively new member of the family. In fact, it was just in 1997 that the seedsman Frank Morton was awarded and credited for this new strain. That same time, this variety was listed as one of the 5 Best New Vegetable Introductions in the U.S. National Gardening Trials.
