Flower Expo is the B2B cannabis trade show built on one premise: brands meet buyers. Launched in Massachusetts in 2023 by a Hall of Flowers alum, it curates invitation-only, state-market floors — Illinois, Massachusetts, New York — where licensed brands, wholesale buyers and actual product samples share the same room.
The Hall of Flowers Family Tree
Founder Jason Bello grew up inside the trade-show business. He was raised in Las Vegas, where his father worked the COMDEX era before moving to Las Vegas Sands and later becoming a founding partner of Hall of Flowers, the California B2B show that set the standard for curated cannabis floors.
Bello worked at Hall of Flowers himself — he was hands-on in launching its Palm Springs edition — then ran sales at Source Cannabis and Green Street Festival before starting his own show. Flower Expo is the East Coast branch of that lineage: same wholesale DNA, different markets.
A First Year That Proved the Point
The 2023 debut at the Franklin County Fairgrounds in Greenfield, Massachusetts landed hard for a first-year show: more than 150 exhibitors, with buyers representing an estimated 70 percent of the state's dispensaries walking the floor. Business actually closed there — exhibitors came away citing signed accounts, not just scanned badges.
Year two ran it back in June 2024 with a floor built around names like Cresco Labs, PAX, Green Thumb Industries, Nova Farms and MariMed, then added a Michigan debut that August to test the playbook in the Midwest's most crowded market. Reps from Green Thumb, Holistic Industries and Glorious Cannabis have all publicly credited the show with new store accounts.
Sampling Is the Feature
Flower Expo is private, invitation-only and 21-plus, and it leans into what most conventions engineer out: consumption and sampling. Buyers evaluate flower and product on site, which is precisely the pitch — supply meets demand, samples in hand, order sheets open. The show's own trademark line, Brands Meet Buyers, is a literal floor plan.
Bello's shorthand for it is a giant farmer's market, and that is the honest energy of the thing: growers showing harvests, buyers tasting, deals closing on the spot. A Speaker Series runs alongside the floor, but nobody pretends the panels are the product — the meetings are.
Where It Runs Now
The next stop is Flower Expo Illinois at The Geraghty in Chicago, September 15–16, 2026. Massachusetts has moved from Greenfield to the Three County Fairgrounds in Northampton — the 2026 edition ran there in June, and the next is set for June 16–17, 2027. A New Jersey edition ran in April 2026, a New York show returns in 2027, and exhibitor and buyer applications run through the official Flower Expo site.
Why It Matters
Most cannabis conventions sell square footage; Flower Expo sells matchmaking. Keeping the floor curated and the buyers vetted makes it the East Coast's closest cousin to the Hall of Flowers model — small enough to work a room, serious enough that the room can stock a state.
The map discipline is part of the model, too. Michigan and Missouri editions now sit in the site's archive while Illinois, Massachusetts and New York carry the calendar — a team pruning markets to where the buyers are instead of stretching the brand thin across every new state.
For a brand fighting for shelf space in Illinois or Massachusetts, this is the two days where a season's distribution can actually get written. Just do not show up expecting a festival — the doors are closed to the public, and the floor is there to work.
