Description
The layered onion is a hardy perennial that produces small bulbils in airy tiers above the stem instead of flowers—hence its name. These bulbils can be harvested or replanted, so no seed sowing is required. It provides flavorful onion greens almost year‑round and is extremely winter hardy.
Care instructions
Plant the airy bulbils in late summer or autumn in a sunny spot; they will root over winter. Leave some stems with bulbils standing so they will self‑multiply. Harvest the tubular leaves continuously from May onward and split overcrowded clumps every few years in spring.
