This season
Blackberries and cut-your-own zinnias are picking, and the sunflower path opened around 12 August. Blueberries are finished for the season. The farm prices by the container: blackberries $8 a pint, $14 a quart, $25 for a two-quart basket.

Swann Farms in northern Calvert County publishes a weekly field report and a full price list, which almost nothing else in this region does.
In the farm's own words, "We price by the container":
The farm posts a "Fresh From the Field Update" by the week, with field conditions written out plainly. Read that before travelling.
There is a published photography policy, so check it before bringing a camera crew.
Pro tip: $14 a quart for blackberries is not cheap, and the farm is upfront about it. What you are buying is a well-run field with fruit actually on the canes in late August, which after this spring is worth something.
We list what we have confirmed. If something you need is not shown, it is worth calling the farm to check.
Our own assessment, scored the same way for every farm on the site, from what each farm publishes about itself. Not a visit, and not a public review score.
