New Zealand Spinach Seeds – Heat Tolerant Heirloom Non-GMO Vegetable, 100 Seeds

New Zealand Spinach (Tetragonia tetragonioides) is a warm-season leafy green that thrives where traditional spinach struggles. Unlike common spinach, which bolts in summer heat, this hardy heirloom keeps producing tender, succulent leaves through the hottest months. Its mild, spinach-like flavor makes it a versatile substitute in salads, sautés, soups, and casseroles. The plant forms a low, spreading mound of thick, triangular green leaves, making it an attractive and productive addition to vegetable beds, borders, and container gardens.

Also known as warrigal greens, this non-GMO heirloom is a reliable choice for gardeners seeking a continuous harvest of fresh greens. It is easy to grow from seed and tolerates heat, humidity, and poor soil better than many cool-season crops. Whether you are extending your leafy green season or trying a new garden vegetable, New Zealand Spinach is a rewarding and low-maintenance option.

Planting & Care

New Zealand Spinach seeds benefit from soaking in water for 24 hours before sowing to soften the hard seed coat. Direct sow outdoors after the last frost date, when soil has warmed to at least 60°F (15°C). Plant seeds about 1/2 inch deep and 3–4 inches apart, thinning to 18–24 inches once seedlings are established. Choose a sunny location with well-drained soil. Keep the seedbed consistently moist until germination, which typically occurs in 10–20 days.

Once established, New Zealand Spinach is relatively drought-tolerant but produces best with regular watering. Mulch around plants to retain moisture and suppress weeds. Harvest young leaves and tender tips as needed; regular picking encourages bushier growth. Leaves can be eaten raw in salads or cooked like spinach. For best flavor, harvest before the plant sets seed. In frost-free climates, plants may self-seed or overwinter as a perennial.
