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.
No seeds in 2022; will try to collect in late October 2023. At least 20 seeds.
