in Thoreau’s Journal:
Methinks roses oftenest display their bright colors which invariably attract all eyes and betray them, against a dark ground, as the dark green or the shady recesses of other bushes and copes, where they show to best advantage. Their enemies do not spare the open flower for an hour. Hence if for no other reason, their buds are most beautiful. Their promise of perfect and dazzling beauty, when their buds are just beginning to expand, beauty which they can hardly contain, as in most youths, commonly surpasses the fulfillment of their expanded flowers. The color shows fairest and brightest in the bud. The expanded flower has no higher or deeper tint than the swelling bud exposed. This raised a dangerous expectation. The season when wild roses are in bloom should have some preeminence, I think.
