Well Grow Onion Ishikura (Allium Fistulosum)

A single stem Variety with dark green hollow leaves originated from Japan. This Variety doesn´t bulb and keeps its flavor when it matures.
 This perennial oriental bunching onion doesn't produce bulbs but forms clumps of elongated, straight white stems similar spring onions. Alternatively the stems can be earthed up to produce leek-like stems. Onion 'Ishikura' can be harvested when pencil-thin or left to grow as thick as a mature carrot.
