SCHWANEBERG, GERMANY - MAY 02: In this aerial view a special machine cuts the flower heads off tulips at the Degenhardt-Sellmann Spezialkulturen tulip fields near Magdeburg on May 2, 2016 in Schwaneberg, Germany. Removing the flowers leads the tulip plant to put more nutrients into its bulb. The company cultivates up to 10 different strains of tulips on 40 hectares of land to harvest not the flowers but the bulbs.  (Photo by Sean Gallup/Getty Images)
