Eruca vesicaria subsp. sativa 28 days. Arugula is a staple leafy green, and we're very excited about this outstanding variety with a delicious, pungent, peppery flavor. Producing uniform crops of vigorous plants, Green Brigade has appealing, dark green, curled leaves that are oval when young. As the plants mature to 3 ½ inches tall and 5 ½ inches wide, the leaves develop attractive lobes and a semi-savoyed texture. Try Green Brigade as a tasty substitute in raw or lightly cooked spinach recipes. Approximately 200 seeds per ½ gram.
