New Zealand spinach ( Tetragonia tetragonioides ), offered by OSC Seeds

Native to Australia , this heat-loving spinach—often called “New Zealand spinach”—has been cultivated in European and North American gardens for nearly 100 years. Unlike common spinach, it tolerates heat and drought very well , making it an excellent summer alternative. Its small, pointed, thick, and tender leaves grow on wide, spreading plants, providing a continuous harvest. It also tolerates salty soils , making it even more versatile.
Note: Due to the presence of oxalates, it is advisable to blanch the leaves before consumption if used in large quantities.

Planting and maintenance:
Sow when the soil is thoroughly warmed, as this plant loves heat . Soak the seeds for 12–24 hours to improve germination. Plant in full sun in well-drained soil. Space the plants 45–60 cm apart, as they spread widely. Water regularly at first, then moderately once established. Harvest by cutting the tender shoots , which encourages continuous production throughout the summer.
