Tatsoi seeds

Tatsoi (Brassica rapa var. rosularis), the highly prized Asian heirloom leafy green celebrated for its striking, broad rosette formation and thick, spoon-shaped, deep emerald leaves. Fast-growing and exceptionally cold-hardy, Tatsoi delivers a tender texture and mild, buttery brassica flavor with subtle mustard undertones—making it a gourmet favorite for both homesteaders and market growers.

Thriving in cool shoulder seasons, Tatsoi forms a dense, ground-hugging rosette during autumn and winter, while remaining compact and upright in warmer weather. Rich in vitamins A, C, and K, calcium, and iron, the succulent leaves are perfect for harvesting young as a baby-leaf salad additive, or mature for stir-fries, soups, steamed side dishes, and sautéed greens.

• Gourmet Texture & Flavor: Tender, mild, and buttery with a satisfying crisp crunch in the thick white stems.

• Exceptional Cold-Hardiness: Endures frosts and continues producing lush green foliage right through winter.

• Striking Rosette Growth: Forms an exquisite, ground-hugging spoon-leaf arrangement that looks stunning in garden beds.

• Cut-and-Come-Again Harvests: Harvest individual outer leaves for continuous growth or pick the full head at maturity.

• Rapid Growth Rate: Yields tender baby leaves in as little as 20–25 days from sowing.

Harvest outer leaves regularly to prolong production or cut the plant 2cm above soil level for a second flush.
