(55 days, Heirloom) Lark’s tongue kale is an old and very tasty German kale variety. This cultivar from the 1800s is actually called ‘Lerchenzungen’. It grows as tall as 2-3 ft. and has slender, elongated, slightly ruffled leaves. Plants are bolt resistant, hardy, easy to grow, contain a lot of vitamin C and are very decorative as well. This uncomplicated cool weather vegetable can be planted in early spring, harvested early as baby kale, and continuing throughout the season up until a hard frost, although best eaten in spring and fall. It’s a popular choice for companion planting, often grown over potatoes or with tomatoes, as all three crops need lots of nutrients. Prolonged frost improves the taste while summer heat makes for tougher, less flavorful leaves with decreased sugar content. Harvest leaves from the outside inwards.
