“Fifty Plants that Changed the Course of History,” by Carol Gravens.

Carol Gravens, now retired from a professional career as a microbiologist, is an Advanced Level St. Louis Master Gardener. She became a Master Naturalist in 2007 and has an AAS in Horticulture from STLCC, Meramec. She has volunteered at the Kemper Center for Home Gardening at the Plant Doctor desk, and the MBG orchid range.
Her presentation will discuss the remarkable interconnection of plants and human existence; that includes the obvious ones like food, shelter, fuel, medicines, clothing, oxygen, and carbon dioxide. But there is more. Carol focuses her talk on a subset of the 50 plants that are detailed in Bill Laws’ book, Fifty Plants that Changed the Course of History.
