New Zealand Spinach

New Zealand spinach, botanically known as Tetragonia tetragonioides, is a warm-season perennial that's often grown as an annual in cooler climates like the UK. It's not a true spinach, but it has similar-tasting, edible, fleshy, and slightly succulent leaves that can be used in salads or cooked like spinach. It's known for its heat tolerance, making it a good alternative for spinach during the summer months.
