Tests on a type of cabbage species called field mustard, a close relative of oilseed rape, showed that when pollinated by bumblebees, the plants grew three inches taller than with hover flies in just nine generations.
They also flowered a day earlier and had double the fragrance. And when placed on ultraviolet light, they had more colours which bees can see.

I don’t in any way mean to disparage the noble field mustard, but did they experiment with any other types of flowers before announcing this?
I have no idea, sorry!
