Allium stellatum (Prairie Onion) [20 Seeds]


Germination Information: I recommend these seeds for experienced seed-sowers only, because they can require a good bit of patience (figure on a few years from sowing to reach flowering size). It’s much quicker to start with purchased bulbs, but if you can’t find them or don’t mind the wait, seeds are worth a try. Sow them in fall to midwinter, just covered with growing medium, and set the pot outdoors to germinate when conditions are right. (I’ve had good luck using the winter-sowing technique with this species.) If you sow much after mid-January, give the seeds an artificial chilling period of about 2 months.

Long-flowering annuals and perennials are a great source of late-season color, but it’s so nice to have some something new to enjoy too. Prairie onion (Allium stellatum) is a real treat for the autumn garden, with globes of starry, rosy pink blooms atop 1-foot-tall stems over narrow, green leaves. Here at Hayefield (in southeastern PA), its slender stems start to rise in mid- to late July, with a distinct nod to each, then gradually straighten up and flower from early September to mid-October. In southern gardens, apparently, it flowers earlier: more like late summer. As with many other alliums, it has interesting dried seedheads, and it can self-sow if you leave the seedheads in place. Prairie onion is native to central North America. Full sun. Zone 3 to 8.

Collected in mid October 2023. At least 20 seeds. Unknown ecotype. Shipping to US addresses only.
