Hollister House Garden in Washington and the Garden Conservancy will co-sponsor the third annual garden study weekend Aug. 24-26. This year's event will examine the topic of "Gardening Anew: Fresh Perspectives on the Garden."

The featured speaker will be internationally renowned landscape designer Edwina von Gal, who will be joined by several professional horticulturists.

The speakers will address a variety of ideas on new ways to garden encompassing the knowledgeable use of native plants with attention to their form and function, solutions found in the soil and examples of thinking outside the box in the spirit of experimentation and innovation.

The three-day event will include a cocktail party, an all-day seminar, plant and book sales, a champagne breakfast and garden tours.

The cocktail party will be held Aug. 24 at Washington Montessori School on Route 202 in Washington.

The Aug. 25 symposium at the school will feature lectures, a buffet lunch and the sale of books and plants. Stephen Orr, editorial director of gardening at Martha Stewart Living, popular blogger and author of "Tomorrow's Garden: Designs and Inspiration for a New Age of Sustainable Gardening," will moderate the conversation and welcome each lecturer.

In addition to Ms. von Gal, speakers will include William Culina, Eric T. Fleisher and Bill Thomas.

Leading horticulturists Page Dickey, Marco Polo Stufano and Adam Wheeler, will offer expertise during a show and tell demonstration at the plant sale.

The champagne breakfast will be held Aug. 26 at Hollister House on Nettleton Hollow Road.

In addition, garden tours, including those at four private gardens in nearby Litchfield and Roxbury, and Hollister House will be offered.
