Hall of Flowers is a curated cannabis trade show that puts licensed brands in front of dispensary buyers. Co-founder Rama Mayo launched it in 2018 at the Sonoma County Fairgrounds in Santa Rosa, and the show now runs editions in New York City and Sacramento.
The 2026 calendar opened in Ventura in March and continues in New York City on October 21–22, 2026, and Sacramento on November 4–5, 2026, the first Hall of Flowers ever staged in California's capital.
Eight years at the Sonoma County Fairgrounds
From 2018 the California show lived at the Sonoma County Fairgrounds in Santa Rosa, where the fall show ran each year. In May 2026 the organizers announced the move to Sacramento, ending an eight-year run in Sonoma County.
Mayo framed the change as a push for a more connected and accessible experience for the industry. Organizers pointed to Sacramento's flight access, hotel inventory and central location, and to the number of retailers, operators and brands already based around the capital.
From Ventura to New York City
Hall of Flowers has stretched beyond Sonoma County more than once. The organizers staged editions in Palm Springs and Ventura, with a Ventura show in March 2024 and again in March 2026. The first New York City edition followed in October 2025, taking the format to the East Coast for the first time.
The 2026 New York show returns on October 21–22, two weeks before the Sacramento debut.
The 2024 Santa Rosa edition
The 2024 Santa Rosa show changed the format for one year. It gathered 320 brands, drew about 3,000 attendees on its business day and opened a second day to the public as a Cannabis Market & Festival that drew about 7,000 more.
That day produced a world-record simultaneous consumption event with roughly 7,000 participants. It also brought an art installation called The Plant is Present, inspired by Marina Abramović, a sold-out Sonoma Hills Farm dining room and a games area built with Exploding Kittens and Joking Hazard.
Brands and buyers on the floor
Exhibiting is by application. Each brand is reviewed for fit with the show's standards, and booth formats range from turnkey spaces to larger custom footprints on a floor plan designed around retailer traffic and product discovery. The organizers describe the show as operating at the intersection of the culture and the industry.
Licensed retail buyers attend free after vetting. A buyer needs an active retail license, or, for a store not yet open, a building permit and city approval. A dedicated retail relations team recruits dispensary buyers in each market so decision-makers fill the aisles.
Industry credentials in New York
New York admission is restricted to cannabis industry professionals with proper credentials. The two-day industry ticket is reserved for verified operators, while a separate Day 2 ticket covers the trade show floor and brand booths. Agencies, service providers and solicitors do not qualify for industry passes, and on-site pitching is off the table.
Where a show adds a public Day 2, the Iconoclasts speaker series is part of that festival programming. Qualified media can apply for complimentary press passes, with applications reviewed weekly.
Where Hall of Flowers sits on the calendar
Hall of Flowers is one of several B2B stops on the West Coast circuit. The Hall of Flowers 2026 guide covers why both editions matter for buyers, and the show sits alongside MJBizCon 2026 in Las Vegas and California's High Supply Show, which focuses on the supply chain side of the trade.
Sacramento outlet Respect My Region covered the move from Santa Rosa when the Sacramento dates were announced in 2026.
