Do you know about the Pacific Northwest Hardy Fern Foundation? It was established to introduce and test the world’s temperate ferns for hardiness and ornamental value and to build comprehensive collections for public display, information and education.
The primary study garden is at the Rhododendron Species Botanical Garden in Federal Way, Washington. The Society has an annual Fern Festival in early June. In recent years, in partnership with the British Pteridological Society, members have joined in fern forays to the west and east coasts of the United States and throughout the world.
