Growing bunching onions (also known as scallions, spring onions, or green onions) from seed is amazingly easy. The entire plant is edible, and onion lovers can?t resist their juicy sweet green tops, delicate stems, and small globe-shaped white bulbs. White Lisbon has been a popular variety for decades, because it produces vigorously and reliably in widely varying conditions. It thrives in a wide range of soils, is heat and cold tolerant, and can be planted in spring, later summer or fall. For the finest quality, pencil-thin onions, sow seed thickly and do not thin.
