Reaching harvestable size in just three weeks, Astro Salad Arugula lives up to its name by delivering speed without sacrificing quality. The heat tolerance sets it apart from slower varieties that bolt quickly in summer, while its open-pollinated genetics mean you can save seed year after year. The bush growth habit keeps plants tidy and manageable in both garden beds and containers, and the ability to regrow after cutting means a single sowing can produce multiple harvests across 5, 14 days of regrowth.
Astro Salad Arugula is primarily used as a tender salad green, harvested at 3, 6 inches for mild, peppery leaves perfect for tossing into mixed greens or dressed simply with olive oil and vinegar. The fast turnaround and regrowth capability also make it valuable for microgreens and successive plantings in kitchen gardens. Once flowering begins, the peppery character intensifies; both the mature leaves and the edible flowers can be used in cooked dishes or as garnish for those seeking sharper flavor.

Direct sow arugula seeds outdoors where plants will grow, pressing them lightly into fertile, well-drained soil. Sow from spring through fall in most zones, or from late summer through early fall for winter greenhouse and high tunnel production. Seeds germinate quickly given the short 21-day harvest window.
Begin harvesting when leaves reach 3, 6 inches in size, typically around day 21 from sowing. Use a sharp knife to cut about an inch above the soil, making sure to cut above the basal plate to allow the plant to regrow cleanly. This cutting method enables a second harvest 5, 14 days later when plants return to desired size. After flowering, leaves become noticeably sharper in flavor but remain edible, and the flowers themselves are also edible.
