This ancient herb moves fast; you'll be harvesting tender, peppery leaves within a month of planting. The finely curled foliage has a delicate, clover-green appearance that makes it as visually appealing as it is flavorful. Curled Cress has been used in herbal traditions across civilizations, and its peppery bite adds complexity to fresh greens and garnishes in ways that standard lettuces simply cannot match.
Curled Cress is harvested young for its tender leaves, which deliver a sharp, peppery bite when eaten fresh. The delicate foliage works beautifully as a salad green, a peppery garnish for soups and sandwiches, or in mixed greens to add complexity and heat. Its quick maturity makes it ideal for cutting in succession plantings throughout the season, providing continuous harvests of spicy microgreens and baby leaves.

Curled Cress can be started indoors 3-4 weeks before your last spring frost. Sow seeds on the soil surface or press them lightly into moist seed-starting mix, as they need light to germinate. Keep soil temperature around 60-70°F and maintain consistent moisture. Transplant seedlings outdoors once they develop their first true leaves and nighttime temperatures stay above 50°F.
Harden off seedlings for 7-10 days in a sheltered location with increasing light exposure. Transplant outdoors when soil can be worked, ideally 2-3 weeks before your last spring frost. Space plants 6 inches apart in full sun. Soil temperature of 50°F or warmer is acceptable, though cress prefers cooler conditions.
Direct sow seeds in early spring as soon as soil is workable, pressing them lightly into moist soil since they require light to germinate. Succession plant every 2-3 weeks through mid-spring and resume in late summer for fall harvest. In cooler zones, you can continue planting into early fall for extended harvests.
Begin harvesting 30-39 days after planting once the clover-like leaves are tender and fully formed. You can harvest the entire plant by cutting it just above soil level, or pick outer leaves individually to encourage continued growth. For the most tender, peppery leaves, harvest in the morning and use fresh; the leaves become tougher and more intensely peppery as the plant ages.
No pruning is necessary for curled cress. Its upright growth habit and rapid maturity mean you'll harvest the entire plant or pick outer leaves selectively before it reaches full size.
