It normally grows to around 30–50 cm in height and is native to Australia.[1] 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.[2] L. australis is one of just a few plants in which the cyanogenic glucoside known as lotaustralin naturally occurs.[3]References1. ^{{cite web|url=http://www.catalog.slsa.sa.gov.au:80/record=b1658722~S1R |title=Plants of the Adelaide plains and hills| publisher=Library of South Australia| accessdate=21 March 2011}} {{Taxonbar|from1=Q3336383}}2. ^{{cite web|url=http://www.slsa.sa.gov.au/site/page.cfm |title=The Native Plants of Adelaide |publisher=Department for Environment and Heritage |accessdate=21 March 2011 |deadurl=yes |archiveurl=https://web.archive.org/web/20110315113933/http://www.slsa.sa.gov.au/site/page.cfm |archivedate=15 March 2011 |df= }} 3. ^{{cite web| url=http://www.scbt.com/datasheet-207835-lotaustralin.html| title=Lotaustralin: sc-207835| publisher=santa cruz biotechnology, inc.| accessdate=16 April 2011}} 2 : Lotus (genus)|Flora of Australia |
