About Scallion

Scallions (green onions) are the fastest, easiest crop in any garden — sow a pinch and cut fresh in as little as three weeks. Grows in almost any sunny spot or container.

Direct sow thickly and thin as you harvest, or regrow from kitchen scraps in a glass of water. Succession-plant every 2-3 weeks for a continuous supply.
