Spent a rainy Sunday afternoon at the #southlondonbotanicalinstitute in #tulsehill, open day (thank you @whitehouseofwhitehouse for finding out about it and insisting we must go). The institute was established by #AllanOctavianHume, one of founders of the #IndianNationalCongress in 1910. Though it had a bumpy century since it survived thanks to the volunteers who have helped its restoration. I met their president and author Roy Vickery, whose book of the folk uses of herbs has just been published by @orionbooks #weidenfeldandnicolson #vickerysfolkflora, a vast must-buy guide to plants and their uses in folk medicine and society.
