The Trustees of Reservations is sponsoring an illustrated lecture and workshop at Long Hill Horticultural Center in Beverly, Massachusetts on Tuesday, September 15, from 6:30 – 8:30 pm.  You’ll learn how to artfully combine shrubs and small trees with a selection of perennial and annual herbaceous plants, and to create a border garden with four seasons of beauty.  Horticulturist and landscape designer Laura Eisner will illustrate basic design principles you can apply to planning and planting a mixed border of any size and shape.  Also covered will be a range of native North American plants that thrive in borders.  Along with plant attributes and drawbacks, Laura will talk about those difficult areas where your plants never seem to thrive and she will discuss which plants will do well there.  Co-sponsored with the New England Wild Flower Society.  Members of the Trusees or NEWFS $25, nonmembers $30.  Registration required.  Contact bzschau@ttor.org.  Log on to www.thetrustees.org for directions.
