On March 1, the 2014 Philadelphia Flower Show kicked off its new theme, "ARTiculture," a mashup of art and horticulture that features original pieces inspired by famous art. The annual indoor flower show, hosted by the Pennsylvania Horticultural Society, is one the oldest and largest of its kind. Each year, the theme changes. Previous themes include 'Brilliant!' (2013), 'Hawaii: Islands of Aloha' (2012), and 'Springtime in Paris' (2011). The Philadelphia Flower Show runs until March 9 at the Pennsylvania Convention Center.
