in Thoreau’s Journal:

What a rich book might be made about buds, including perhaps, sprouts. The impregnable, vivacious willow catkins, but half asleep along the twigs, under the armor of their black scales, the birch and oak sprouts, the rank and lusty dogwood sprouts, the sound, red buds of the blueberry, the small pointed red buds, close to the twig, of the panicled andromeda, the large yellowish buds of the swamp pink, etc. How healthy and vivacious must he be who would treat of these things.
