"I have never grasped why some folk are so desperate to have a perfectly uniform, green lawn, unmarred by pretty flowers. The concept of a ‘weed’ is entirely within our heads; one man’s weed is another’s beautiful wildflower. If we could somehow engineer a shift in attitude, so that ‘weeds’ such as daisies or clovers were seen as desirable additions to a lawn, rather than enemies to be battled against, we would save ourselves an awful lot of time, money and stress, while helping nature into the bargain."
