Colza is in bloom now in France.
Here's what wikipedia has to say:
Colza oil is a nondrying oil obtained from the seeds of Brassica rapa, var. oleifera, a variety of the plant that produces turnips. Colza is extensively cultivated in France, Belgium, the United States, the Netherlands and Germany and Poland. In France, especially, the extraction of the oil is an important industry. In commerce, colza is classed with rapeseed oil, to which it is very closely allied in both source and properties. It is a comparatively nonodoriferous oil of a yellow colour, having a specific gravity varying between 0.912 and 0.920. The cake left after extraction of the oil is a valuable feed ingredient for pigs.
