2018 California Spring Trials Dates, Times, Locations

California CoastExpect some celebration along the California coast at the 2018 California Spring Trials (CAST), held April 14 to April 19. Three breeders – Benary, Hem Genetics, and Speedling – will celebrate major anniversaries this year. Not to mention there will be wonderful displays, great food, good company, and new varieties to look forward to seeing.

As you prepare for your trip, don’t forget to call ahead and schedule appointments with each trial. Some breeders have their own registration sites and others use a central website. Please note that American Hort will not manage the registration site this year. For select companies, this will done through Clarity Connect at SpringTrialsRegistration.com. Registration opened Jan. 2. Most sites are open 8:00 a.m. to 5:00 p.m. daily, but a few have limited hours. Be sure to check the schedules as opening and closing times may vary.


Here are a few changes to note for this year:

  • Ball Horticultural Co. will have a shortened schedule this year. It will not be open on April 18.
  • While Floranova/Vegetalis is next door to Green Fuse Botanicals, each company will present separately. You will need to schedule an appointment with each one individually.
