Orchids are wildly fascinating. Whether you enjoy them on a purely aesthetic level or delve more deeply into the evolution and specialization of certain species, you cannot help but draw a deep sense of satisfaction from these plants.

Perhaps you’ve heard of the legendary Darwin’s Orchid, Angraecum sesquipedale. This lovely Madagascar native’s large, star-shaped flowers are annual jaw-droppers in the NYBG’s Orchid Showoften drawing throngs of eager fans and photographers. As the story goes, Charles Darwin studied the narrow, 10-15” long, nectar-filled spur that hangs from the rear of each flower, surmising that whichever creature fed on the nectar (and subsequently pollinated the orchid) must posses a proboscis of truly epic proportion. His hypothesis was largely ignored or ridiculed, leaving the mystery of the Angraecum pollinator to remain unsolved for decades. Unfortunately, Darwin would not survive to see his theory substantiated.
