Centaurea americana ‘White’ (White American Basket Flower) [15 Seeds]


Germination Information: Sow the seeds about 1/4 inch deep, either indoors in early to mid spring or directly in your garden after your average last frost date. Cutting off the finished flowers can extend the bloom season, but if you leave some of them on the plants to form seeds, they will likely self-sow.

American basket flower (Centaurea americana) gets its common name from the intricate, overlapping scales that encircle the base of each powder-puff bloom, creating a basket-like effect. The large, thistle-like blooms, which close at night, typically have white centers surrounded by a purplish pink outer ring. I collected these seeds from plants that produced all-white flowers. They were growing near the purplish pink species, though, and pollinators happily visit both, so it’s possible that these seeds may produce a mix of the two colors. The blooms appear through summer atop stems that can top out anywhere from 2 to 5 feet tall (figure on the shorter side of that range in average soil and the taller side in rich, moist conditions). Full sun. Annual.

Collected in August 2020. At least 15 seeds.
