Famous quotes containing the word plants:
“We have been God-like in our planned breeding of our domesticated plants and animals, but we have been rabbit-like in our unplanned breeding of ourselves.”
—A.J. (Arnold Joseph)
“When the
Marne flowed by the plants nodded
And above the glistering Gila
A sunset as beautiful as the Athabasca
Stammered. The Zambezi chimed. The Oxus
Flowed somewhere.”
—John Ashbery (b. 1927)
