Nothing lasts, and already the plum blossoms are beginning to fall.
As each petal falls,
The branches of the plum
While they are blooming the branches look fresh and young. But as the petals begin to fall, we see the twisted, black branches beneath; and the more the petals fall, the older the branches seem to become, and of course the passing of the blossoms adds to that effect as this brief moment of spring, like all things, passes.
