We must learn not to disassociate the airy flower from the earthy root, for the flower that is cut off from its root fades, and its seeds are barren, whereas the root, secure in mother earth, can produce flower after flower and bring their fruit to maturity.
--The Kabbalah
When all is said and done, is there any more wonderful sight, any moment when man's reason is nearer to some sort of contact with the nature of the world than the sowing of seeds, the planting of cuttings, the transplanting of shrubs or the grafting of slips?
--St. Augustine of Hippo
--Chinese proverb
--Thomas Hill
