Mark Your Calendars For The 2016 California Spring Trials

California Coast

2016 California Spring Trials will be held from Saturday, April 9 through Thursday, April 14. As you plan your trip, make sure to call ahead to schedule appointments with each trial site. You can find contact and registration information at and check americanhort/ for updates. Appointments can be scheduled on the Horticulture Events website for a select number of breeders; others require you to contact them directly.


Generally, most locations are open from 8 a.m. to 5 p.m.; however, check the schedules on the Horticulture Events website as opening and closing times may vary.

Dümmen Orange will again have two locations this year, and Suntory will join GroLink. EuroAmerican Propagators will return to its home location in Bonsall, CA, and hold an open house April 7-9, which will include in-ground trials from several breeders. Floranova and Vegetalis have opted out this year due to the opening of the new Floranova research site in Chile. Finally, note that Proven Winners is moving from the Chaminade Resort and Spa in Santa Cruz to the Kirigin Cellars Winery in Gilroy.
