As its name suggests, this biennial cousin of kale (technically, it’s a mustard) is grown as a leafy green in Ethiopia. The leaves have a milder flavour than either kale or mustard, but are rich in nutrients. The plants are cold hardy and drought resistant. Grow for tasty, nutritious baby greens or full size leaves. The full sized leaves benefit from blanching or stir-frying to become tender and tasty.
