Emerald City Orchids owner Joseph Grienauer tells the sexy and seedy history of Orchids

Orchids have many pollinators, such as moths, beetles, birds, wasps and bees. But one pollinator surpasses them all – the human. Our tale begins with the first orchid to bloom in a greenhouse in the late 18th century. It continues through 200 years of human cultivation which leads to new methods of hybridization and eventually cloning. It is a tale of amazing natural phenomena, human ingenuity, and of course, drama. Orchid expert Joe Grienauer will explore the history of the complex relationship between humans and orchids, including instances of murder, sexual repressions, revenge, greed, and redemption.
