“How to Successfully Grow Dahlias and Sweet Peas”

We are so exited to welcome the exceptional local flower grower and author Marryn Mathis to tell us all things about growing sweet peas and dahlias. Marryn, known for her incredible dahlia field and amazing sweet peas, is also a cut flower educator who created the very unique sweet pea school. At her flower farm she specializes in seed production, growing cut flowers for retail, dahlia hybridization and educational workshops. Now the “Queen of Growing Sweet Peas” has published a new book: Sweet Pea School: Growing and Arranging the Garden’s Most Romantic Blooms that will be available at our lecture.

The Whatcom Horticultural Society sponsors a variety of programs, events, lectures, tours, and publications for Whatcom County area gardeners.

We welcome the novice and the veteran; active gardeners and those who love to visit, discuss and read about gardens; those who are visitors; those who are new to the area and those deeply entrenched. We hope we have something of value to offer you all.

WHS was organized in 1989 and was originally known as the Whatcom in Bloom Garden Society. The name was changed to avoid confusion with the Whatcom County Parks annual friendly garden competition, called Whatcom County in Bloom.

Members are encouraged to participate in WHS activities, especially as volunteers during the summer Annual Tour of Private Gardens.
