Several times a year the Botanical Garden hosts these extensive displays. Flora Borealis is a dramatic light and sound show that winds around the grounds featuring laser lights and an extensive sound system. I had the opportunity to tour the grounds with other photographers and a special guide that showed us photographic opportunities. If you are interested in taking more than iPhone photos, be sure to check out Missouri Botanical Garden’s website for the photo opportunities.
