Famous quotes containing the word plants:

    He who plants a tree
    Plants a hope.
    Lucy Larcom (1826–1893)

    Probably if our lives were more conformed to nature, we should not need to defend ourselves against her heats and colds, but find her our constant nurse and friend, as do plants and quadrupeds.
    Henry David Thoreau (1817–1862)

    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.
