Farewell, old friend.

Join more than 2,000 seed industry professionals from over 30 countries for America's largest seed industry conference! A time-honored tradition each December, this year's CSS & Seed Expo will be our last year holding the event in Chicago, where it has been held since 1946. Don't miss this special year when we bid a fond farewell to our historical host city!

Last year to exhibit in Chicago!

Now that the pandemic has subsided enough to allow for it, we are bringing our exhibitors back together again into Riverside Center! Don't miss the chance for our exhibitor community to literally come together one last time at the Hyatt Regency Chicago, where the event has been held since 1977.
