A volunteer (or as Magnes says.. a "hit and run" lol) of this plant showed up near my bird feeders this spring. I left it where they planted it because I recognized it as a Brassica. This family of plants are host for a few species of "White" butterflies, wherein their larvae depend on them to survive.
One is the Cabbage White which I have already observed on this plant.

Several other species of butterflies and bees have been visiting it as well.

This looks good in the fields when in flower but it seeds everywhere and appears in the cracks in paving even in towns. Can be invasive.

The town of Tisdale, Saskatchewan, Canada is well known for their honey and their many fields of rapeseed or canola. Signs coming into Tisdale, proclaim Tisdale as "The land of rape and honey". This is where I grew up, so mass fields of yellow was a very common sight for me.
