lawn, n.Trivia

Lawns before WWII were usually a mix of grass and clover. Herbicide companies in the 50s mounted a major advertising campaign to convince homeowners clover was a weed, because their new herbicides killed clover but not grass

The scent of freshly-mowed grass is the lawn actually trying to save itself from injury by releasing a number of volatile organic compounds.

Dandelions are regarded as weeds today due to the rise of lawn culture and marketing by pesticide companies.
