If you have a garden and a library, you have everything you need. From "To Varro, in Ad Familiares IX, 4".
The original latin is: Si hortum in bibliotheca habes, nihil deerit.
Marcus Tullius Cicero (3 January 106 – 7 December 43 BC) was a Roman statesman, lawyer, scholar and Academic skeptic who played an important role in the politics of the late Roman Republic and in vain tried to uphold republican principles during the crises that led to the establishment of the Roman Empire. His extensive writings include treatises on rhetoric, philosophy and politics, and he is considered one of Rome's greatest orators and prose stylists.
The leaves are perfect for all year round use in the garden, hanging from trees, fixed to a wall or fence.
