Orange Is The New Red in the Sunken Garden! The Holiday Flower Show tradition began in 1925 and continues to be the most anticipated and visited flower attraction at the Conservatory today. It is a visual sensation to behold featuring hundreds of poinsettias. Orange is the new red in the 2014 Holiday Show and will feature a new Poinsettia called Autumn Leaves, a beautiful mix of yellow and pink bracts. The show will be complimented with the following Poinsettia cultivars: Orange Spice, Maren, Marco Polo, Premium Apricot, and Sparkling Punch to give the show more orange, pinks, cinnamon and apricot colors. The two toned yellow Coleus Wild Lime will accent the poinsettias.
