Sylvetta
Diplotaxis tenuifolia
vegetableSylvetta, also known as wild rocket or arugula, is a Mediterranean leafy green with deeply lobed, feathery leaves and a peppery, slightly nutty flavor. It's more robust and cold-hardy than cultivated arugula, with smaller leaves and a more intense taste. This fast-growing crop is ideal for quick harvests and successive plantings throughout the growing season.

Seedling
7-10 daysTiny cotyledons emerge, followed by the first true leaves with characteristic serrated edges
Thin seedlings to proper spacing once they have 2-3 true leaves. Keep soil moist but not soggy to prevent damping off.
Vegetative Growth
15-20 daysMultiple lobed leaves develop in a rosette pattern; plant grows rapidly with vigorous green foliage
Ensure consistent watering and adequate light. Feed every 2-3 weeks with balanced fertilizer if soil is not rich in organic matter.
Baby Leaf Harvest
20-25 days from plantingLeaves reach 3-4 inches in length with tender, delicate texture and full peppery flavor
Begin harvesting outer leaves from the bottom, or use scissors to cut entire plants at soil level for microgreens. Harvest in early morning for best flavor.
Mature Leaf Stage
30-50 days from plantingFully developed, deeply lobed feathery leaves reach 4-8 inches; plant becomes bushier and more robust
Continue harvesting outer leaves to encourage continued growth and delay bolting. Keep soil consistently moist.
Flowering & Bolt
2-3 weeks (timing depends on temperature and day length)Plant sends up tall flower stems with small white or light yellow four-petaled flowers; leaves become tougher and more bitter
Harvest remaining leaves before or just as flowering begins. Can allow a few plants to flower for seed production or to feed pollinators.

Uses
Fresh salads and peppery greens
CulinarySylvetta's peppery, slightly nutty flavor makes it excellent in fresh salads, as a garnish, and in mixed green dishes. The delicate baby leaves are particularly prized for salads, while mature leaves work well in cooked dishes. [source]
Pesto and sauces

Harvest Tips
Begin harvesting 20-25 days from planting for tender baby leaves. Cut outer leaves individually with scissors, or cut the entire plant 1-2 inches above soil level for continuous regrowth. Harvest in the morning for optimal flavor and crispness. Successive plantings every 2-3 weeks ensure continuous supply. Flavor is most tender and mild before flowering; once flowers appear, leaves become tough and bitter. Frost actually improves flavor by increasing sugars.
Fun Facts
- 🌱 Sylvetta is the original wild arugula and is hardier and more cold-tolerant than the cultivated Eruca variety, making it ideal for fall, winter, and early spring gardening in many regions.
- 🌱 The name 'sylvetta' comes from the Italian word 'selvatica,' meaning 'wild,' reflecting its origins as a Mediterranean wild plant valued for centuries in Italian and Mediterranean cuisines.
- 🌱 Sylvetta's peppery flavor intensifies in cool weather and after frost, as the plant increases sugar production as a natural antifreeze, making late-season harvests particularly flavorful.
