Salad Greens include our mustards, orach, arugula, shungiku, cress, endive, frisee, claytonia, and much more. Plant in rows, spacing seeds 2" or 5 cm apart. Thin as they mature, using the thinnings in your salad, and then harvest tender young leaves from the crown of each plant. Replant as the patches age. May be planted in a planter box or directly into the ground.
