Green onion

Overview

Also called scallions or spring onions, green onions are harvested before the bulb fully develops, prized for their mild flavor and versatile crunch. They are among the fastest and easiest alliums to grow, ready in as little as 60 days from seed. Many varieties are perennial, forming ever-expanding clumps that can be harvested year after year.
