Weeds in advertising: GM China

A giant field full of dandelion heads releasing their seeds in the wind, who would have thought of that as an ad for GM? Link to image and info: Print advertisement for GM China by Bates Advertising.

I guess GM wants the symbolism of all the green, as in green = good, or is it something about weeds spreading far and taking over?

(species: dandelion, Taraxacum officinale, Asteraceae)
