Dori Smith, M.Ed., Gardens for Life, will present an illustrated lecture on Sunday, June 6, from 1 – 3 pm, at Tower Hill Botanic Garden, 11 French Drive, Boylston, Massachusetts.  Would you like to help protect our precious water resources, while at the same time create a lush, beautiful garden that attracts birds and butterflies?  Rain gardens take advantage our our natural abundance of rainfall, rather than wasting it as runoff.  Rain gardens use water flowing from your roof, driveway, or lawn.  These gardens are easy care, and can often solve problems such as erosion, icy walkways, or wet basements.   Dori will review design options, construction details, and appropriate native plants.  The class will then take a walk around the Wildlife Pond to see some of the outstanding plants recommended for rain gardens.  Tower Hill members: $18, non-members, $20.  To register, or for more information, log on to www.towerhillbg.org.  Dori will be a featured speaker for The Garden Club of the Back Bay next April, but if you have limited weekday availability, this Tower Hill lecture is the session to attend.
