A perennial trailing plant mainly grown as a half-hardy annual in the UK. It is tolerant of high temperatures unlike regular spinach but is frost tender (although I have grown in a polytunnel in Devon as a self-seeding perennial with positive results). An interesting triangular shaped leaf that is fleshy, succulent-like and slightly salty to taste. Can be used as spinach (although unrelated) and its trailing habit makes for good ground cover. High in oxalic acid - should be eaten in small quantities when raw.
