True spinach (English spinach) is a cool-season annual prized for its tender, dark green leaves. It is one of the most nutritious leafy greens but also one of the most temperamental to grow in Australian conditions. It bolts rapidly in heat and long day-lengths, making it primarily an autumn-winter-early spring crop across most of Australia. Understanding this limitation is key to successful growing.
