Downers Grove, IL — National Garden Bureau (NGB), manager for the California Spring Trials (CAST) is pleased to announce the date for the 2027 event as April 6-9, 2027. This is Week 14, one week later than the 2026 event in Week 13 because of religious holidays.
This key industry event for brokers, growers, and retailers will again be held at multiple locations across California, offering an exclusive preview of upcoming ornamental and edible plant introductions. One key location change for 2027 is that the Ball Companies will now be at the Museum of Ventura County, in downtown Santa Paula, approximately 4 miles from their old location. If any other locations or participants change, additional releases, as well as the CAST website, will provide that information.
For those who missed the 2026 event, breeder summaries and trade media coverage are available at caspringtrials.us.
Multiple attendees at the 2026 event have recorded videos explaining why they attend CAST and give their recommendations about why you should attend as well.
Plan now to attend CAST 2027 – the condensed locations mean you can now complete your trip in just 3 days!
For all the super-advanced planners, CAST 2028 will be back to Week 13 with the dates of March 28-31, 2028.
