“If you have a garden and a library,” said the Roman philosopher Cicero, “you have everything you need.” These are wise conditions under which to live a life: With books to connect you to humanity, and plants to connect you to nature. And as reading is a lifetime joy—one at which we get better with age—gardening is the same. To cultivate a garden for food or for beauty is a skill one can employ into the farthest reaches of old age. And, it is our luck that we may turn to our library, and peer through the pages of a gardening book, to bolster this passion.
