Heirloom Ishikura Onion Seeds

Ishikura reaches enormous proportions (to two feet tall, one inch across) while remaining tender and scallion-like, never forming a bulb. A perfect heat- and cold-tolerant green that is a go-to choice to grow alongside Asian greens in the cool season! No garden should be without this easy-to-grow culinary staple!
