USA - Friends of the Rogerson Clematis Collection (FRCC)

One of the largest collections of clematis in the USA is located in the Portland area in Oregon, USA. The clematis are displayed in a garden setting with a number of different areas focusing on specific clematis. The garden is well worth a visit and is open to visitors every day from 8:00 am to dusk. The greenhouse (staffed with volunteers) is open Fridays 10:00 am to 2:00 pm and the 4th Saturday of the month 10:00 am to 1:00 pm. There is always something to see even in winter. The Collection updates its web site regularly with the flowers that are in bloom. Please see the FRCC web site for the latest information on opening hours and what is in bloom at

Members of the International Clematis Society who visited Portland, Oregon, USA in 2010 or 2001 with the Society can't fail to remember the Clematis Collection of Brewster Rogerson. The range of cultivars and loving care that each had obviously received was very impressive.

Started in 1978 with just sixty plants it then contained 900 plants representing over 500 different cultivars. To safeguard its future, it was moved in 2005 to a new location at Luscher Farm in West Linn, a neighboring suburb to Lake Oswego in Oregon, USA.

The maintenance and upkeep of such a collection is a very significant task that cannot but get more burdensome with age. Recognizing the importance of this collection, Brewster and some of the members of the Pacific Northwest Clematis Society formed the "Friends of the Rogerson Clematis Collection".

The mission of this organization is:- "to preserve and foster the collection in a permanent home, observing its longtime objectives of assembling and maintaining as comprehensive a collection of the genus Clematis as possible, for the advancement of botanical and horticultural research and the education and pleasure of all who visit it."

The collection contains some of the oldest and latest cultivars, as well as some very rare species not usually on show.

As a result of a vote of the members of the Pacific Northwest Clematis Society in October 2006, from 1 January 2007 the PNCS was incorporated within the FRCC.
