Some crops are vivid green others are yellow.  Canola.  The plant has tough long stems and the leaves form on the lower parts of the plant. Stray plants grow along the road sides. Yellow fades away before harvest next month. 

There is talk of a bumper crop state wide with time constraints while a shortage of workers is feared and compounded by state border closures which prevent the movement of labour and machinery. Flexibility is unknown.  Canola is also know as rapeseed and was grown as cattle food earlier on. So this is the ingredient in spreads and other foods. Polyunsaturated fats are sought but more on the exact status of canola has slipped the mind.
