Sylvetta Arugula (diplotaxis tenufolia). This perennial heirloom originated in Italy. Often referred to as Wild Arugula, it is a full season grower. This plant forms small bushes, with multi-stems loaded with small 2 inch very pointy olive green leaves. This zesty salad addition stays productive right through summer. The yellow flowers are mild and delicious. Mulch cover to overwinter. Easy from seed, direct plant in spring.
