Onion Long White Ishikura

Onion Long White Ishikura

RHS Award

Spring Onion Ishikura is a Japanese bunching type of  onion. It produces long white stalks with short green tops which can be pulled when they are as thin as a pencil or as thick as a carrot. It doesn't form a bulb so looks almost like a young leek. It has a fine mild flavour to it which makes it ideal for salads or stir frys.
