How to Grow Aruguletta

Aruguletta

Diplotaxis tenuifolia

vegetable

Aruguletta is a perennial leafy green closely related to common arugula, featuring smaller, more delicate leaves with a milder, slightly sweet peppery flavor. Native to the Mediterranean region, it's prized by chefs for its tender texture and refined taste. Unlike annual arugula, this variety can regrow multiple harvests over several seasons.

Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout within 5-10 days. Tiny cotyledons emerge, followed by the first true leaves with finely dissected edges.

Keep soil moist but not soggy. Provide bright light immediately after sprouting. Thin seedlings to proper spacing once they have 2-3 true leaves.

2

Vegetative Growth

2-4 weeks

Plant develops rosettes of increasingly delicate, deeply lobed leaves. Growth is relatively vigorous and bushy at this stage.

Water consistently. Fertilize lightly with balanced or nitrogen-rich fertilizer every 2-3 weeks. Ensure adequate airflow to prevent fungal issues. Remove any damaged leaves.

3

Leaf Maturation & First Harvest

1-2 weeks

Inner leaves reach full size and tenderness (3-4 inches long). Plant has developed a substantial rosette ready for harvesting.

Begin harvesting outer leaves once they reach desired size. Cut leaves at soil level or pinch off individual leaves, leaving the center to continue growing. This stimulates branching and fuller regrowth.

4

Continuous Harvest & Regrowth

Months (spring through fall, or year-round in mild zones)

Plant produces successive flushes of new leaves throughout the season. In mild climates, can produce for months.

Harvest the outer leaves regularly to encourage continued production. Deadhead any flower buds that form to extend the vegetative stage. Continue regular watering and light feeding.

5

Flowering & End of Season

Variable; allows plant to go to seed or overwinter

Small yellow flowers appear as the plant transitions to reproduction. Leaves may become tougher and more peppery.

If continued leaf production is desired, pinch off flower buds. Allow plants to flower if you want seeds for next season. In perennial zones, cut plant back hard in fall for winter dormancy and spring regrowth.

Common Pests

  • Use row covers on young plants; apply neem oil or spinosad if infestation is severe; encourage beneficial insects like ground beetles

  • Spray with water to dislodge; use insecticidal soap or neem oil; introduce ladybugs or parasitic wasps

  • and

    Remove by hand, especially in early morning; create copper barriers; use diatomaceous earth; provide beer traps

  • Use fine row covers; hand-pick caterpillars; apply Bt (Bacillus thuringiensis) spray; encourage parasitic wasps

  • Ensure good air circulation; avoid overhead watering; spray with sulfur or baking soda solution if needed; remove affected leaves

Uses

🍳

Salads & Fresh Preparations

Culinary

Aruguletta's delicate leaves and mild peppery flavor make it ideal for elegant salads, as a microgreen, and as a fresh garnish for pasta, risotto, and seafood dishes. Its tender texture and refined taste are preferred by fine dining chefs. [source]

🍳

Pesto & Sauces

Culinary

Blend aruguletta into pesto, aioli, or chimichurri for a sophisticated, mildly peppery sauce. Use it as a base for butter or cream sauce for vegetables and proteins. [source]

💊

Anti-inflammatory & Digestive Support

Medicinal

Like other cruciferous greens, aruguletta contains glucosinolates and isothiocyanates with potential anti-inflammatory and antioxidant properties. Traditional use supports digestive health and may have cancer-preventive compounds. [source]

🦋

Pollinator & Beneficial Insect Support

Wildlife

Allowing aruguletta to flower provides nectar and pollen for bees, butterflies, and other beneficial insects. The flowers are small, delicate, and attractive to pollinators. [source]

🏠

Microgreens Production

Household

Aruguletta is an excellent microgreen crop, ready to harvest in 1-2 weeks. It adds peppery flavor and visual appeal to sandwiches, soups, and plated dishes with minimal space required. [source]

Harvest Tips

Begin harvesting when leaves are 2-3 inches long, typically 30-45 days after sowing. Use the 'cut and come again' method: harvest outer leaves at the base using a sharp knife or pinch them off by hand, leaving the inner crown intact to continue producing. Early morning harvest yields the crispest, most tender leaves. In hot weather, harvest in early morning or evening to catch cooler temperatures. For perennial management, cut back the entire plant by half every 6-8 weeks to rejuvenate growth and prevent flowering.

Fun Facts

  • 🌱 Aruguletta (Diplotaxis tenuifolia) is technically a perennial or short-lived biennial, unlike common arugula (Eruca vesicaria) which is an annual—it can produce for multiple years in mild climates with proper management.
  • 🌱 The name 'aruguletta' means 'little arugula' in Italian, referring to its smaller, more delicate leaves compared to standard arugula. Italians value it highly in fine cuisine.
  • 🌱 Aruguletta flowers are bright yellow and edible, adding a peppery bite and visual appeal to salads. Chef David Chang and other high-profile chefs have popularized this variety in upscale restaurants.
