Registration is now open for the 2026 California Spring Trials, which take place March 24-27, 2026, along the California coast. For the second year in a row, the National Garden Bureau is managing registration for the event, where several of the world’s leading plant breeders highlight what’s coming in new plant varieties and series.
The CAST website allows you to easily view each trial location before registering. One person can create a detailed itinerary and then easily add an unlimited number of traveling companions by providing their name, company, email address, and any dietary restrictions. This ensures everyone in your group follows the same schedule.
