I found this quote from Saint Francis of Assisi in the monks' garden at the old Santa Barbara Mission. It says,
"He even said that the brother gardener ought to reserve a place in the corner for a beautiful small garden where he puts all kinds of aromatic herbs and flowering plants so that they in their season might invite all men who looked at them to praise God...For every creature says and proclaims, 'God has created me for you, O man."
I want to make one for the corner of my garden.
