Next Year's Flowers: Saving Seeds at Struan Farm

The sunflower patch at Struan Farm is starting to finish its season, with the earlier flowers dipping their heads downward and turning brown. I'm trying to save the seeds to plant next year, so have decapitated a number and put the heads in the garden shed to dry out:

Still deciding about what to plant in the sunflower patch during the winter. Right now we're thinking it may be winter vegetables.
