Sunflowers are good fun! We’re yet to work out the “grand plan” for the gardens at the front of the house, but we did have a spare patch of soil. In went sunflowers, four of which germinated. A few weeks ago flowers unfurled, bringing joy to everyone who walks by.
Seed saving tips from the Seed Savers Handbook: “Pick the heads when the petals have withered … Cut the heads, tie them in bundles and dry in the sun for a week or more … For a smaller crop, heads can be rubbed by hand. Clean the seeds by winnowing and sieving.”
Apparently the seeds will last up to 5 years when dried well. They can, of course, also be eaten!
