About

Native to Asia, it is a perennial onion that does not form large bulbs, producing dense clumps of hollow, cylindrical stems. It allows continuous harvesting throughout almost the entire year without killing the plant. It works very well as a protective border against pests in the food forest.

It is harvested now — July is one of the harvest months.
