Longwood Gardens had an exhibit of over 13,00 lilies in their fabulous Conservatory in 2011. The exhibit was named Lilytopia. The lilies were grown in the Netherlands by fifteen different breeding houses and were flown to Longwood overnight for the largest exhibit of lilies ever in the U.S. The event was planned for over a year and displayed designer grade lilies rarely seen outside of the Netherlands. It was truly incredible.
