New Zealand Spinach Seeds

Tetragonia tetragonioides

New Zealand spinach (Tetragonia tetragonioides), also known as Warrigal greens, is a heat-tolerant leafy green that is often used as a substitute for true spinach (Spinacia oleracea). It belongs to the Aizoaceae family, which includes many drought-resistant plants. This plant thrives in warm climates where traditional spinach struggles, making it a valuable crop for summer greens.

Perennial in warm climates but grown as an annual in cooler regions.
Sprawling growth habit, with thick, triangular, succulent-like leaves.
Prefers well-drained soil and can tolerate coastal conditions and drought.
Requires blanching before consumption to reduce oxalates.

Used like spinach in soups, stir-fries, and salads (after blanching).
High in vitamins A and C, as well as antioxidants.
Historically used to prevent scurvy due to its vitamin C content.

Indigenous Use: Native to New Zealand, Australia, and parts of Asia. It was used by Indigenous peoples for food and medicinal purposes.
European Discovery: Captain James Cook and his crew documented and used it in the 18th century to combat scurvy during their voyages. Cook encouraged its use, and seeds were later introduced to Europe.
Spread to Gardens: By the late 18th and early 19th centuries, New Zealand spinach was grown in European and American gardens as a warm-season spinach alternative.
Modern Use: Now grown worldwide in home gardens and permaculture systems due to its resilience and productivity.
