Numerous cultivars are grown throughout the temperate regions of the world. Most
are utilised as a food source for humans, domestic animals and in the brewing

all states and territories. Individuals may form short-lived populations in the
vicinity of cultivated H. vulgare, or where its seed is used as fodder,
for example stock yards. Flowers mainly Aug.-Oct.
