lecture: the well-mannered perennial garden

Tuesday, September 16, 7pm

An artfully designed perennial garden can be a delight. But for a perennial garden to reach its full potential, it must be managed after planting with great care and understanding. Successful perennial gardens do not happen by accident. How do you know, for example,, which plants need to be pinched back? And when? Which perennials tend to be thuggish and what can you do? What plants are best suited for the hot, humid summers? Join garden designer Harriet Cramer to learn what you can do to sidestep frustration to ensure that your garden is a source of pride and pleasure.

Cramer Design Associates was started in 1996 by Harriet Cramer. She has a B.A. from Franklin and Marshall College and an M.A. from Johns Hopkins University. Following a career in international banking, Harriet decided to pursue her lifelong love of horticulture by completing the Barnes Foundation's Horticulture Program. She then worked as a volunteer, and later as an employee, at the Morris Arboretum of the Univ. of PA, where she still lectures. In 1997, her book The Shadier Garden was published, and in 1998 she collaborated on Garden Blueprints. She also writes for Fine Gardening, Horticulture, and Green Scene magazines.
