Fast, Mild & Incredibly Versatile — The Green That Does It All
Meet the green that bridges the gap between spinach and mustard — and outperforms both in the summer garden. Mustard Spinach 'Tendergreen' is a heat-tolerant, fast-growing leafy green with large, smooth, deep green leaves and a mild, slightly mustardy flavor that's far more approachable than traditional mustard greens. It's the go-to green for gardeners who want spinach-like versatility without spinach's intolerance for heat. Botanical Interests brings you this reliable variety in a non-GMO, open-pollinated form.
Mustard Spinach (Brassica rapa var. perviridis), also known as Komatsuna or Japanese Mustard Spinach, is a staple of Asian cuisine and an increasingly popular choice in Western gardens for its productivity, adaptability, and nutritional density. 'Tendergreen' is one of the mildest, most versatile selections — equally delicious raw in salads, stir-fried, steamed, or added to soups.

Growing Tips
Direct sow outdoors in early spring through summer, or in late summer for a fall harvest. Sow seeds ¼–½ inch deep and thin to 6–8 inches apart. Mustard Spinach prefers full sun to partial shade and consistent moisture. Harvest baby leaves at 3–4 inches for the mildest flavor, or allow to grow to full size for a more robust taste. For cooking, harvest larger leaves and use as you would spinach or bok choy — it wilts down significantly and pairs beautifully with garlic, sesame, and soy. Succession sow every 2–3 weeks for a continuous harvest throughout the season.
