Aladdin's magic lamp burned oil that was a forerunner of canola oil.  When canola is in flower the country-side looks crazily sports minded wearing the green and gold. It is our third largest broadacre crop after wheat and barley.
At flowering time the crop has implications for honey bees.

Related to the brassica family with a name derived from Canadian Oil low acid, the Canola plants develope multiple seed pods, like runner beans, which change from green to brown to black so it seems that the crop is brown and dry by the time of windrow and large harvesters.

The seeds from the pods are crushed and precessed in various ways to produce oil and substances that have very diverse uses in foods and in industry.

GM canola is also grown.  Resistence to herbicides is a feature.  There are reports of the growth of hugh weeds as a result of how things are done.

The oil is said to have health benefits over other fats.
A multinational company, Cargell, with HQ in Minneapollis, has widespread operations in canola in Australia and at Kooragang in Newcastle has a crush plant and oil refinery and oil terminal complete with a smell of cooking oil.
One local organization among others, GrainCorp Oil, is to start producing and exporting the oil and the seeds.
