A spreading herbaceous species which forms clumps of up to 1 metre in height and 1.5 metres in diameter. Spreads by underground rhizomes and often forms dense swathes. Leaves are tough or leathery and can reach 85 centimetres in length, though 30-50 cm is more usual. Flowers are carried in loose clusters on tall flower spikes which exceed the foliage in height. Each flower is blue with yellow filaments and brown or black anthers. Flowers are followed by green fruits which turn a vivid blue at maturity. Each contains several dark, glossy seeds.
Propagation by seed gives variable results and seed may take months to germinate. Soaking in soapy water or smoke water may enhance germination, as may lightly scratching the seed coat. Propagation can also be carried out by dividing the underground rhizomes.
Chiefly September and October.
Ubiquitous in reserves and by roadsides.
