Evergreen Bunching Heshiko Onion (Heirloom, 65 Days)
Heirloom. The Evergreen Bunching Heshiko Onion produces no bulbs and also divides and thus can be considered sort of a perennial. Can be sown thickly (20 seeds per square foot) either in the spring for a fall crop or in the fall for a crop the following year. Use like scallions, then allow some plants to grow and each will have half a dozen narrow divisions in the fall.

Cure them in the sun for a few days then finish drying them out of direct sunlight, in a warm area, and in single layer so air can circulate around them until the neck is dry. Store in a cool dark place with 35-40ºF temperatures and 65-70% humidity.
