Volunteer lupins

The most common volunteer lupins are narrow leaf lupins (Lupinus angustifolius), (also know as blue lupins), which are found growing in winter crops (mostly cereals) areas of Australia where lupins are grown. Lupins are grown in rotation with cereals as both a disease break and for their nitrogen fixing ability. Albus lupins (Lupinus albus) (also known as white lupins) are an important crop in some areas although the total area grown across Australia is much less than the area of narrow leaf lupins. The WA blue lupin (Lupinus cosentinii) was introduced for summer grazing and thrives on poor sandy soils and is now considered a weed.
