“Unless a tree has borne blossoms in spring, you will vainly look for fruit on it in autumn”

“When nature has work to be done, she creates a genius to do it”

“What would be ugly in a garden constitutes beauty in a mountain”

“We may brave human laws, but we cannot resist natural ones”

“A morning-glory at my window satisfies me more than the metaphysics of books”
