A novel Japanese salad onion with extremely thick tubular foliage. Plants given a wider spacing can achieve huge stems similar to leeks. The flavour is unusually sweet lower in the stems and more pungent towards the leaves.
Winter hardy.
Sow March to August, every 4 weeks. Sow thinly in broad drills, about 1cm (½in) deep, allowing 30cm (12in) between drills.
Draw up soil to larger stems as you would for leeks. Keep well watered during dry periods.
For years onions have been used as one of the oldest medicines for their anti-bacterial, antiseptic and anti-asthmatic properties. They have also shown to lower blood pressure and cholesterol levels.
Dual purpose as a Spring Onion or as a 'leek' for salads, stir fries and cooked dishes.
