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.

    The holly and the ivy
    Are plants that are well known
    Of all the trees that grow in the woods
    The holly bears the crown.
    —Unknown. The Holly and the Ivy (l. 1–4)

    Brute force crushes many plants. Yet the plants rise again. The Pyramids will not last a moment compared with the daisy. And before Buddha or Jesus spoke the nightingale sang, and long after the words of Jesus and Buddha are gone into oblivion the nightingale still will sing. Because it is neither preaching nor commanding nor urging. It is just singing. And in the beginning was not a Word, but a chirrup.
    —D.H. (David Herbert)
