Hall of Flowers, the invite-only cannabis trade show that built a devoted following at the Sonoma County Fairgrounds, is packing up its pipes and leaving Santa Rosa, shifting its Northern California event to Sacramento this fall. Organizers have set Nov. 4–5, 2026 for the relocated show, which will cap an eight-year run in Wine Country.
Those dates now appear on the Hall of Flowers site, which lists Sacramento as the Northern California stop for 2026, and a press release announcing the relocation was picked up by industry outlets including mg Magazine.
Organizers say access and connectivity drove the decision
In a company post, co-founder Rama Mayo said the move "reflects our desire to create an even more connected, accessible and dynamic experience for the industry," as shared on LinkedIn. The show also notes that "Participation is selective. Each exhibiting brand is reviewed to ensure alignment with the quality and standards of the show," language on the Hall of Flowers exhibitor page that organizers say preserves a buyer-focused floor.
Local leaders call it a loss for Sonoma County
Local tourism officials told The Press Democrat that the trade show's departure is a loss for the county, and the paper quoted longtime tourism executive Tim Zahner saying the region "does not yet have the cultural critical mass to make cannabis a major tourist attraction." Sonoma County Tourism has been promoting cannabis experiences and lodging packages as part of its visitor strategy, underscoring what officials say the area stands to lose from the move. Visitor information on Sonoma County Tourism shows how the county has tied cannabis into wellness and lodging offerings.
From smoke-outs to an East Coast debut
Hall of Flowers began at the Sonoma County Fairgrounds in 2018 and has since branched into other markets, staging a Ventura edition in March 2024 and making its East Coast debut in New York City in October 2025, according to event listings and industry coverage. The show's profile in Santa Rosa was especially visible in 2024 when organizers and partners staged a world-record smoke session, with roughly 7,000 participants lighting joints simultaneously, an event The Press Democrat covered in which Mayo said "the energy was electric, the vibe was unparalleled." Industry outlets from trade magazines to national cannabis press tracked the show's expansion and the shift toward a hybrid business-and-festival model; Leafly covered the New York debut and marketplace implications.
What's next for exhibitors and visitors
Organizers have not announced a Sacramento venue yet and instead point exhibitors and buyers to the event site and mailing list for floor plans and travel packages ahead of the November dates. For Sonoma vendors and hospitality businesses, the move is a prompt to rethink when and where they meet buyers and to watch how Sacramento absorbs a show that has become a major fixture for premium cannabis brands.
