Well-formed, golden-skinned onions appear in abundance, and mature early in the season. An RHS AGM award-winner, onion 'Centurion' are strong and easy to grow, and once harvested, the onions store well, so can be enjoyed over a long period.


  • Garden care:
    Plant onion sets so that the tips are just showing, and then firm the soil around them from mid-February to March, 15cm (6in) apart in rows 30cm (12in) apart. Lift the onions when they are mature (normally in August) and allow them to dry before using. Store the fully ripened, sound bulbs in nets or trays and you can use them throughout the autumn and winter.
