The Massachusetts Horticultural Society continues its “Wednesday Evening” series at Elm Bank, 900 Washington Street, Wellesley, with Suzanne Mahler speaking on the topic Fabulous Flowers and Foliage for Summer Gardens. Everyone’s garden looks terrific in June, but careful choices made early in the season can ensure that the beds you have at the beginning of summer still looks great in July and August, when our gardens become tired. Foliage (Persian shield, below) has a major role to play in a good-looking mid- and late-summer garden. Suzanne’s own garden is a testament to how ‘summer’ means more than June beauty.  All “Wednesday Evenings” talks begin at 7 p.m. and are held in the Education Building at Elm Bank. They end when the last question is answered.  The cost to Mass Hort members is $10 per talk or $50 for the series of ten. The charge for non-Mass Hort members is $15 per talk. Refreshments and beverages are served at all talks.  Reservations are not required.  For directions and more information, visit www.masshort.org.
