The 2021 California Summer Trials, scheduled for June 23-27, mark a few changes with the annual California pilgrimage for growers, brokers and breeders.
To begin, there’s the obvious one: when it’s happening.
Historically, the acronym CAST has stood for the California Spring Trials with the event taking place sometime in the early spring over the course of a week. In 2020, the event just so happened to coincide with the beginning of the ongoing COVID-19 pandemic. As a result, the event did not happen with the various stops across the state shuttered. By virtue of unfortunate timing, CAST 2020 was the first horticulture industry event directly impacted by the pandemic. Each stop canceled its showcase and long-booked plans largely fell by the wayside. Some breeders, however, were able to pivot to digital and host webinars to showcase new varieties, but others were left with no real outlet to market their plants.
The 2021 event is scheduled for June for specific reasons. One is COVID-19 and the hope that the event wouldn’t have to be canceled again due to the virus. At the time of this publication, that appears to be a winning bet. The idea was to, in theory, allow more people to attend during a slower time of the year instead of the peak spring. And, as an added bonus, early summer means a larger diversity of crops — such as perennials and annuals that perform well in the heat — to be spotlighted in a more normal growing climate.
CAST 2021 also sees a different shape to the event with the number of participating breeders dropping. This shift actually began in 2020 when Proven Winners declined to participate, even before COVID-19 was a concern. (Proven Winners announced its decision not to participate in CAST 2020 in July 2019.) Citing declining attendance and a desire to “broaden the pool” of industry members who were able to participate, Proven Winners went digital while still planning to showcase its varieties at other industry events. For 2021, Danziger and Terra Nova Nurseries are among the breeders declining to participate, and it’s unclear if any will re-join the event in the future.
Benary, which is participating in the event, also made changes. Instead of limiting visitors to the official five-day window of CAST 2021, its gardens are open through Aug. 31 to anyone who books a visit ahead of time. The idea here is to not exclude a grower or someone else who maybe can’t make it in June, but could come later on in the summer.
In this preview, you’ll find information on all of the stops, as well as some of the new varieties that will be on display at CAST 2021. And if you’re planning on attending or are just planning to observe from afar, we’d love to hear from you. Drop us a line at email@example.com. – Chris Manning
