Tendersweet carrot Seeds. Non-GMO. Heirloom. Organic. Aptly named Tendersweet for its tender 9-10" roots and its unmatched sugar content, next to sugar beet, Tendersweet carrot is truly one of the sweetest root vegetables in the garden. A century-old American heirloom, Tendersweet has served as the parent crop to countless of hybrids, boasting the same sweetness, just as delicious raw as when cooked. They are coreless and delicious, perfect for canning, juicing, or eating raw.
