Onion chives, someone was stingy with the seeds, they do best in sun, probably grow best in Mt summer, I cannot keep onion chives alive for a whole year, our summer hits triple digits and they go extinct in July and August. On the other hand, my garlic chives have survived 5 yrs. My onion chives do okay under snow cover, but won't survive ice. Probably best to simply keep reseeding.
