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

Description 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. (I’ll note that they appear identical to the strain sold as ‘Aloha White’.) They were growing separate from the purplish pink species, but pollinators happily visit both, so there’s a small chance that these seeds may produce a few pink-flowered plants. 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 2025. At least 15 seeds. Shipping to U.S. addresses only. Please read the germination information as well before ordering.
