Onion, Shallot & Garlic Sets


In this range you'll find spring-planting, autumn-planting and heat-treated varieties. Spring-planting varieties will give you a crop during June and July and autumn-planting varieties will be ready a few weeks earlier. Spring is such a busy time and planting onions and garlic in the autumn to overwinter gives you one less job to in spring! Heat-treated onions are less likely to bolt (run to seed) on planting, which occurs particularly in red varieties.

  • Onion 'Red Arrow' – An early red onion with rosy red skins and pink tinged flesh, which makes a colourful contribution to many culinary dishes.
  • Onion 'Vulcan' – An earlier-ripening onion hybrid. The golden skinned, deep, rounded bulbs have firm flesh and store well, for up to 12 weeks after harvesting.
