Crab apple blossoms.

"Those which lately even I tasted only to repent of it,—for I am semi-civilized,—which the farmer willingly left on the tree, I am now glad to find have the property of hanging on like the leaves of the young oaks... Let the frost come to freeze them first, solid as stones, and then the rain or a warm winter day to thaw them, and they will seem to have borrowed a flavor from heaven through the medium of the air in which they hang." #Thoreau #WildApples
