Dandelions manage it. They are vegetables, or a least plants. Left to their own devices, dandelions will grown nearly 12 inches tall, flower, go to seed, and propagate themselves.
But, make one pass with a lawnmower and it learns 'em. After getting mowed, the dandelions change their life strategy, and grow low to the ground and flower low to the ground, too low for the mower to mow them. Dandelions learn from the first pass of the lawn mower.
Smarter than the average weed.
