"If you can tempt Judith Sumner to address your group, you are in for a fantastic treat! She wowed us. Her talk on herbal medicine was both intellectually stimulating and hilariously funny. We learned so much as Judith addressed myths and misinformation associated with herbs as well as truths and potential uses. Her historical perspectives and humor-filled style made her one of the best speakers we have ever had. Five stars!!!"


"Thoroughly entertaining speaker who combines her academic background with an engaging approach to plants and their history. I have now heard her speak in two very different settings——the first, a garden club in a small city setting, and the second, a Master Gardeners conference in rural Maine. And she was a hit at both. A refreshing break from the usual fare!"

See Judith on the Martha Stewart Living television show, discussing the botany of Aloe vera:
