Worked out from 30 years of climate records for Cowirra. Microclimates vary: frost hollows and hills run later.
A long-lived perennial grown for its tart stalks, planted as crowns in winter or from seedlings in spring. It needs rich soil, plenty of water in summer and some afternoon shade in hot Adelaide weather. Only the stalks are edible: the leaves are toxic.
