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

(1 customer review)


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. In my experience, it is normal for the germination to be erratic. The first seedling(s) usually pops up in within a week or so in warm conditions, with others showing up over the next few weeks. (Last time I sowed these seeds, I started them indoors on April 11. The first seedling appeared on April 15, another on April 18, and another on April 19 [today]). I find that germination tends to be poor in hot weather.

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 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 mid- to late August 2023. At least 15 seeds.
