'White Lisbon' is a green or spring onion, and sometimes referred to as a scallion or bunching onion. A popular variety since the 1700s because it produces dependably in widely varying conditions. It thrives in a wide range of soils, is heat and cold tolerant, and can be sown successively throughout the season. For the finest quality, pencil-thin onions, sow seed densely and do not thin seedlings.
