Weeds want no sowing.

A weed is a plant that has mastered every survival skill except to be able to grow in rows

It is not the business of the botanist to eradicate the weeds. Enough for him if he can tell us just how fast they grow.

A weed is but an unloved flower.

What is a weed? A plant whose virtues have not yet been discovered.

Remember this, my friends: there are no such things as bad plants or bad men. There are only bad cultivators.

In the garden of ethics, even the smallest weeds can choke out the tallest flowers.

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.

the Indians, were like the weeds. That roses you had to water and give fertilizer or they’d die. But weeds, indigenous plants, you gave them nada-nothing; hell, you even poisoned them and put concrete over them, and those weeds would still break the concrete, reaching for the sunlight of God. “That’s the power of our people,” my father would tell me, “we’re the weeds, LAS YERBAS DE TODO EL MUNDO!”

Damn it, Jim, I’m a botanist, not a chemist!

There are no weeds, and no worthless men. There are only bad farmers.

A weed is no more than a flower in disguise.

"These sprays, dusts, and aerosols are now applied almost universally to farms, gardens, forests, and homes - nonselective chemicals that have the power to kill every insect, the "good" and the "bad", to still the song of birds and the leaping of fish in the streams, to coat the leaves with a deadly film, and to linger on in soil - all this though the intended target may be only a few weeds or insects. Can anyone believe it is possible to lay down such a barrage of poisons on the surface of the earth with out making it unfit for all life? They should not be called "insecticides", but "biocides"."
