Diplotaxis erucoides (21 days baby, 50 days mature) Open-pollinated. Also known as Rucola Selvatica, a must for extraordinary cold-season salads. A wild form of arugula, very deeply lobed dark green narrow leaves grow steadily, reaching 3" in 3 weeks, the perfect length for a 7" salad plate. Nutty, sweet, crisp and moderately spicy, Sylvetta grows foliage right to the rib base, no stem to trim. Please your restaurant accounts with this beautifully uniform arugula strain. Slower growing, smaller and more pungent than regular arugula. Out-competed 8 other commercial-production strains in our summer endurance trial. Highly recommended for market farmers and gardeners alike. Eliot Coleman lists it as one of his winter staples in The Winter Harvest Handbook. ~110,000 seeds/oz. Cold-hardy. ②

About 11,700-15,000 seeds/oz. 1⁄16 oz packet sows 60 ft; 1 oz sows 960 ft. Also known as Roquette or Rocket. Musky green and its piquant blossoms will spice up your salad.
Culture: Prefers cool temperatures; direct seed as early as possible in spring. Optimum germination temp 40–55°. Bolts in heat; avoid the heat and grow as a fall crop, or make succession plantings every 1-2 weeks. Use row covers to discourage flea beetles. Let part of a spring crop go to seed and get a self-sown September and October patch that is delicious and has no flea beetle damage! A prime ingredient in tangy mesclun mixes. Frequent watering will reduce its pungency. Suitable for microgreens.
Saving Seed: Saving arugula seed is easy! Let your spring sowing of arugula bolt. The flowers develop into narrow seed pods. Once pods dry on the stems, they can be easily broken open for seed.
Days to maturity are from emergence after direct seeding.
All greens are open-pollinated except where noted.
Culture: When to harvest greens? Research from trials conducted in England and Kenya showed looseleaf lettuce, red chard and arugula harvested in the evening had a longer shelf life than when picked in the morning.
