Move over kale and spinach — there’s a new supergreen winning hearts across the U.S. Known for its rich flavor, vibrant green rosettes, and powerhouse nutrition, Tatsoi is fast becoming a staple in American kitchens, farmers’ markets, and home gardens.
Also called spoon mustard or spinach mustard, Tatsoi (pronounced taht-soy) is an ancient Asian green from the Brassica family — the same family as bok choy and kale. Its smooth, spoon-shaped leaves and mild mustard flavor make it one of the most versatile and nutrient-packed greens you can cook with.
From smoothies and salads to soups and sautés, Tatsoi is the green that fits effortlessly into any modern American diet. Whether you’re a home gardener, a fitness enthusiast, or simply someone who loves fresh and flavorful produce, Tatsoi deserves a spot on your plate — and in your garden.
What Is Tatsoi?
Tatsoi (Brassica rapa var. rosularis) is a cool-season leafy vegetable that originated in Japan and China but is now thriving in American soil. It’s part of the cruciferous family, closely related to bok choy, mustard greens, and arugula.
Visually, Tatsoi is stunning — a low-growing, compact plant that forms a beautiful rosette of dark green, glossy leaves. Its flavor is mild, slightly tangy, and nutty with a hint of mustard spice. The texture is silky yet firm, making it ideal for both raw and cooked dishes.
In the U.S., Tatsoi has quickly gained popularity among chefs and home gardeners because of its adaptability, fast growth, and impressive nutritional profile. It’s often called the “new spinach” — but with more flavor and nutrients packed into every bite.

Why Tatsoi Is Taking Root in American Gardens
One of the biggest reasons for Tatsoi’s popularity in the U.S. is its ease of cultivation. Whether you’re growing it in your backyard, on a balcony, or in a raised garden bed, Tatsoi adapts beautifully to American climates.
How to Grow Tatsoi in the U.S.
- Ideal Climate
Tatsoi thrives in cool weather, making it perfect for spring and fall planting.- In northern states, sow seeds in April–May or August–September.
- In southern states, fall and winter are the best seasons.
- Soil and Sunlight
Use rich, well-drained soil with a pH between 6.0 and 7.5.
Tatsoi grows well in full sun to partial shade — it’s even frost-tolerant, which means it can survive mild American winters! - Planting and Spacing
- Sow seeds about ¼ inch deep and 6 inches apart.
- Thin seedlings to ensure proper airflow and prevent disease.
- Watering and Care
Keep soil consistently moist but not waterlogged. Tatsoi grows fast — you can start harvesting baby leaves in just 25–30 days. - Pest Management
Common pests include aphids and flea beetles. Use organic neem spray or companion plants like mint or dill to deter them naturally.
Tatsoi is one of the few greens that can withstand frost, and some gardeners claim it tastes even sweeter after a light freeze. That makes it a fantastic winter crop for American home growers.
