About Astro
Astro is a fast-growing salad arugula with broad, smooth leaves and a mild, slightly nutty flavor compared with wilder types. It is grown for quick baby-leaf production and stays fairly uniform in the bed.
Growing Astro Arugula
Sow thickly for cut-and-come-again baby greens, or thin for larger bunching leaves. Grow it in cool weather, because heat speeds bolting and makes the flavor sharper.
