 | | WHITE LISBONThe traditional "Spring" onion. White Lisbon boast long white stems with bright green tops that are slow to form a bulb, which contain a delicious mild flavour. Sow little and often from March to July to ensure a fresh, regular supply . |
 | | ISHIKURAOnion 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. |
 | | WHITE LISBON WINTER HARDYThis is a variety that produces the same onion as White Lisbon but has been selected specifically for its winter hardiness making it suitable only for autumn sowing for a spring harvest. The onions that are produced have long white stems with bright green tops and are slow to form a bulb, which contains a delicious mild flavour. |
 | | GUARDSMANA very vigorous development of salad onions. Upright, good looking and winter hardy, it produces a good length of 'white'. Suitable for both autumn and spring sowing, it is slow to bolt and resistant to white rot. |

Outdoor Sowing
Sow spring onion seeds directly outdoors 12mm (1/2 in) deep in spring followed by successional sowings into early summer. Sow 12mm (1/2in) deep in rows 150mm (6in) apart.
Thinning
Thin the onion plants to 25mm (1in) spacing.

Spring-sown spring onions are ready from early summer.
