21 days baby. 40 days full size. Arugula hearkens back to the old-fashioned arugula that pleased so many plates with intense flavors. The nutty pungency is spicy when grown in spring or summer, but balanced, complex, and more mellow when grown in the colder months. Excellent raw in salads, on sandwiches, with apples or pears, or cooked briefly. Extra freeze-hardy to about 6 degrees Fahrenheit and is a must for the Fall or Spring garden. 15,000 seeds /oz. Pkt (~250 seeds) plants 12′.
