Yukina Savoy Seeds – Brassica rapa | Tatsoi-Style Rosette | Cold-Hardy Asian Green

Yukina Savoy (Brassica rapa) is a standout cool-season Asian green that combines the beloved rosette form of tatsoi with larger, more substantial, heavily savoyed (crinkled) leaves and an upright, easy-to-harvest architecture. Thick, dark forest-green, spoon-shaped leaves with pale green petioles — striking in appearance, mild and sweet in flavor. Vigorous and versatile, Yukina Savoy is both heat and cold resistant and can be grown nearly year-round in many climates. Slow to bolt — meaning a longer harvest window and more value per planting. Approximately 21,500 seeds per oz.

Planting Guide

• Soil: Fertile, well-draining. Sow seeds after last frost in spring, or in late summer/early fall for cool-season harvest.
• Sowing depth: ¼–½ inch deep.
• Spacing: Thin to 8–12 inches apart for full rosettes; grow closer for baby leaf production.
• Transplanting: Raise seedlings at 73–75°F (day) and above 53°F (night) until 5–7 true leaves appear. Transplant carefully; water and fertilize consistently after transplanting.
• Vernalization note: Like all Chinese cabbage, Yukina Savoy can bolt if exposed to 41°F for one week, or 50°F for two weeks. Manage planting timing accordingly in spring.
• Watering: Consistent moisture for lush, tender leaf growth. Fertilize as needed.

Harvesting

• Baby greens: Begin harvesting outer leaves from 25 days.
• Full rosettes: Harvest at 45 days by cutting the whole plant cleanly at the base.
• Cut-and-come-again: Pick outer leaves individually for continued production from a single plant.
• Harvest in the morning before heat reduces leaf moisture and texture.
