Saving Seeds From Cosmos | A Simple Guide
Cosmos are one of my favourite flowers — bright, easy to grow, and perfect for pollinators. Saving seeds from your cosmos not only lets you enjoy them next year, but it also helps preserve your favourite varieties. This variety pictured above is Bipanthus, Striped Pink.
