Frequently asked

When is boysenberry season in California?
Boysenberry season in California runs June and July. The boysenberry — a cross of raspberry, blackberry, and loganberry — was developed in Southern California in the 1920s and is most famously associated with Knott's Berry Farm in Buena Park, which built its early reputation on boysenberry preserves. Today, a handful of Central Coast and Northern California farms still grow them for u-pick. The fruit is large, dark maroon to black when ripe, and has a rich, wine-like flavor. Harvest events and U-pick windows follow the same window — check each listing for exact 2026 dates.
Can you pick your own boysenberry in California?
Yes — California has pick-your-own boysenberry farms where you can harvest your own. See the Gather Grove U-pick boysenberry guide for locations and seasons.
Are boysenberry festivals in California free?
It varies — many are free community events, while others are ticketed. Each festival's page on Gather Grove lists its admission.
