Pure white, endlessly generous — flowers from midsummer until the first hard frost. From my own plants, September 2023, stored carefully ever since.
Cosmos has been used since pre-Columbian times as a source of natural dye — the flowers yield yellow and orange when simmered with mordanted cloth. The white Purity variety offers a quieter palette. This is a cut flower: it blooms from midsummer until the first hard frost, and the more you cut, the more it gives. Dry the seed heads in a cool, well-ventilated room away from sunlight and they will hold their shape beautifully for winter arrangements.
