(6:30 pm in Founders Hall on the grounds of Kemper Center.) Her latest book is titled "White Gardens," and explores some of the ways in which one can create a so-called Moon Garden in which most of the flowers are white and look especially beautiful in the moonlight. She has been an adjunct instructor for the Chicago Botanical Gardens and has written for a number of different publications, including the Chicago Tribune.
