A Partnership with the Earth

Last day to purchase tickets - Tuesday, June 14th

Gardens connect us in many different ways. With others who share this same passion, with ourselves as a place of respite and joy, and with the Earth that needs our care and assistance. These connections are vital to gardeners, and add to the pleasure of gardening. NPA’s Hardy Plant Study Weekend is all about exploring these connections.

It's been 4 years since NPA hosted Study Weekend, and we’re thrilled to host again in 2022. This regional gardening event rotates locations with our friends in the Hardy Plant Society of Oregon in Portland, and the Hardy Plant Groups of Vancouver and Victoria in British Columbia.

Study Weekend is filled with top-notch seminar speakers, 31 stunning and inspiring gardens to visit, a plant sale with specialty nurseries, and fun social events where you can enjoy the company of other plant people from all over the Pacific Northwest. This event is open to everyone.
