Mark your calendars now: Rhubarb Days returns June 20-21, 2026, for another unforgettable weekend in downtown Sumner. We can’t wait to see you!
Rhubarb Days brings together all the best things you love about a street fair & festival – 200+ vendors, more than a dozen food trucks, two live music stages, and a kids zone – but with plenty of rhubarb pie & crisp, freshly-cut rhubarb, and even rhubarb-infused craft beer.
Rhubarb Days is presented by Knutson Farms, and powered by Sumner Main Street Association in partnership with City of Sumner.
