Famous quotes containing the word plants:

    So neither the one who plants nor the one who waters is anything, but only God who gives the growth. The one who plants and the one who waters have a common purpose, and each will receive wages according to the labor of each. For we are God’s servants, working together; you are God’s field, God’s building.
    Bible: New Testament, 1 Corinthians 3:7-9.

    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)

    What I did not yet know so intensely was the hatred of the white American for the black, a hatred so deep that I wonder if every white man in this country, when he plants a tree, doesn’t see Negroes hanging from its branches.
    Jean Genet (1910–1986)
