"Like a great poet, nature knows how to product the greatest effects with the most limited means." 

 Heinrich Heine 

"Natural objects themselves, even when they make no claim to beauty, excite the feelings, and occupy the imagination.  Nature pleases, attracts, delights, merely because it is nature.  We recognize in it an Infinite Power."

Karl Wilhelm Humboldt

"We learn from our gardens to deal with the most urgent question of the time: How much is enough?"

Wendell Berry
