Rocket Arugula ( Eruca vesicaria subsp. sativa ) is a fast-growing, cool-season green prized for its bold, peppery flavor and tender, lance-shaped leaves. This classic salad arugula matures quickly, producing abundant foliage with that signature sharp bite perfect for fresh salads, sandwiches, pizzas, and garnishes. Plants grow upright and reliably even in smaller spaces, thriving in early spring and fall when temperatures are cooler. About Rocket Arugula Rocket Arugula is an annual selection of garden arugula, with an upright/erect habit and an expected height or spread of 13–18 in. It is best suited to baby leaf, full-size greens, succession planting, cool-season gardens, and seed saving. Notable traits include cut baby leaves young or harvest full-size plants before quality declines; peppery to mustard-like flavor that strengthens with age and heat. Gardeners comparing named strains should evaluate Rocket Arugula for uniformity, flavor, timing, and plant form rather than assuming another garden arugula will perform identically. History and provenance Peppery salad greens and mustard greens come from several Brassicaceae species. Garden arugula, wild arugula, upland cress, and mustard greens differ in life cycle, leaf texture, and heat tolerance, so this page preserves species-level identity rather than relying on flavor names alone. Arugula Seeds - Rocket Arugula belongs to a plant lineage long associated with Mediterranean and Old World garden agriculture. It was selected over generations for kitchen, market, ornamental, or herbal value and remains useful in modern home gardens. Growing facts Scientific name Eruca vesicaria (L.) Cav. subsp. sativa (Mill.) Thell. Life cycle Annual Maturity 50-59 Days Germination 3-7 Days at 45–60 °F Seed depth 1/4 in Plant height / spread 13–18 in Growth habit Upright/Erect Spacing 6 in between plants; 12 in between rows Sunlight Full - Partial Sun Soil Loamy; pH 6.0–6.5 Water Moderate Support No-Support Starting Rocket Arugula from seed Sow 1/4 in deep and keep the seed zone evenly moist. Expect emergence in 3-7 Days when the seed-zone temperature is near 45–60 °F. Germination preparation: Direct sow into a prepared, weed-free seedbed; avoid disturbing developing roots or dense stands. Light requirement: Cover evenly to 1/4 in. Soaking: None required. Stratification: None required. Scarification: None required. Planting and care Plant during spring and provide full - partial sun. Space plants 6 in apart with 12 in between rows. Use loamy with a pH near 6.0–6.5, and follow a moderate watering plan. Support requirement: No-Support. Frost response: Hardy. Good container fit with drainage, even moisture, and the listed spacing Harvest and use Approximately 50-59 Days, from direct sowing to the listed baby-leaf or full-size harvest stage. Weather, soil temperature, and planting method can shift the actual harvest date. Harvest: Cut baby leaves young or harvest full-size plants before quality declines. Uses: Baby leaf, full-size greens, succession planting, cool-season gardens, and seed saving. Flavor: peppery to mustard-like flavor that strengthens with age and heat. Seed saving: Open-pollinated herb or leafy crop. Best uses include baby leaf, full-size greens, succession planting, cool-season gardens, and seed saving. Flavor and eating quality: peppery to mustard-like flavor that strengthens with age and heat. Saving seed Select several healthy, true-to-type Rocket Arugula plants that match the expected upright/erect habit and overall plant form. Avoid saving seed only from the earliest or largest individual unless that is your deliberate selection goal. Pollination system: Open-pollinated herb or leafy crop. Compatible plants of the same species may cross to varying degrees through insects or wind. Separate compatible varieties that may flower together, or use cages, barriers, hand pollination, or another documented control appropriate to the crop. Allow selected plants to pass the eating stage and reach full botanical seed maturity. Harvest only when seed heads, pods, or fruits have matured enough for sound seed development. Clean the seed carefully, dry it thoroughly away from direct heat, label the lot with variety and year, and store it cool, dark, and dry. Test germination before an important planting or distribution season. Common problems Common concerns: Flea beetles, imported cabbageworm, cabbage loopers, aphids, slugs, root maggots, and clubroot risk where the pathogen is present. Management: Use rotation, insect netting before pests arrive, regular leaf inspection, sanitation, and well-drained soil. Do not plant the same brassica family repeatedly in one bed. Diagnosis note: Similar symptoms can have different causes. Compare plants of the same age, record weather and irrigation, and use local Extension or diagnostic support before applying a control. Frequently asked questions Frequently Asked Questions - Rocket Arugula When is Rocket Arugula ready? Use 50-59 Days. Approximately 50-59 Days, from direct sowing to the listed baby-leaf or full-size harvest stage. Weather, soil temperature, and planting method can shift the actual harvest date. How long does germination take? Expect 3-7 Days at about 45–60 °F. Cooler, hotter, crusted, saturated, or dry seedbeds can slow emergence. How large does it grow? Expect about 13–18 in with an upright/erect habit. Space plants 6 in apart and rows 12 in apart. Support: No-Support. Can it grow in a container? Good container fit with drainage, even moisture, and the listed spacing Use a container with drainage and enough volume to maintain the listed spacing and steady moisture. Can I save seed? Open-pollinated herb or leafy crop. Keep compatible varieties isolated and allow selected plants to reach full seed maturity.
