For Master Gardeners from Christian, Jersey, Macoupin, & Montgomery counties Topic: Plants that Changed the Course of History, Part 2 Presented by: John Hensley Based on a second subset of plants from Bill Laws’ book, Plants that Changed the Course of History, this enlightening and entertaining presentation was prepared by John Hensley in collaboration with Carol Gravens, our presenter of Part 1 in 2022. John has identified additional plants to explore for their important role in our history. John Hensley became a master gardener in St. Louis in 2008 and gardeners rely on him and others who man the Plant Doctor info service. His specialty is lawns, and he has been enjoying donating time at Missouri Botanical Garden every Wednesday.
