NEW: Visit our brand new Rhubarb Days website, rhubarbdays.com! A work in progress, rhubarbdays.com will be continually updated as Sumner’s annual signature festival draws near, with event hours, live music information, food trucks and vendors, event map, sponsors, future event dates and more. Check it out!
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.

Vendor applications:
Vendor applications for Rhubarb Days 2026 have now closed.
BEWARE OF SCAMS AND FRAUDULENT ACTIVITY: We’ve received multiple reports of unauthorized people posting on social media and even emailing our vendors asking for payments to reserve vendor booth space at Rhubarb Days. This is, unfortunately, becoming an annual occurrence. Applications are only accepted via sumnermainstreet.com. Vendors should only respond to emails from events@sumnermainstreet.com or director@sumnermainstreet.com (never from gmail, hotmail, etc.) If you are in doubt, feel free to email or call us directly to confirm.
