Theme of the short story:

In an unnamed place and time, a majestic villa overlooks a garden of delicate, glass-stemmed flowers. Home to Count Axel and the Countess, the otherwise elegant landscape is unsettled by a dark blot on the horizon. It is an army of furious workers, drawing nearer day by day. To slow its approach, Axel plucks the time flowers from his garden; each one dissolves in a burst of light which rewinds time itself, and so the threatening horde shifts back on the skyline. This solution, however, is only temporary. The garden of time is faltering, the flowers are almost all gone, and the masses will soon arrive to take their long-awaited revenge.

Eventually there are no more "time flowers" and the "army of furious workers" over run their little, fake paradise.

In other words: Nothing Can Stop What Is Coming.
