Leaves are of a trifoliate shape and are small, with a light green colour. During spring, the plant bursts into beautiful massed displays of white pea flowers. In summer these are replaced with stiff tubular beans, which explode when they dry, releasing multiple small, black legume seeds. Austral trefoil is easily propagated from these seeds, by soaking the seeds in hot water overnight before sowing. This mimics the heat of a bushfire, which is a contributing factor in germination in the wild.
