Canola is used to make cooking oil, right? California poppies has no such use that I know of. These grow wild like weeds. BTW, the image looks beautiful with rainbow and all.
The photo was taken in the country and was just a fabulous scene. Yes they are used to make cooking oil I was only referring to the fields of colour just like you see with the poppies, not their usage Rapeseed oil is what's made from the Canola plants. Good nutrients for good heart health benefits.
This image reminds me of parts of the midlands, here in Tasmania, that is located in the central plateau area of the Tasmania.
