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 Baron' (Spring Planting)

Allium cepa

 Customer Rating
  • Easy to grow

Spring planting. Heat treated.

A mid-late maturing variety, Onion 'Red Baron' produces firm, flattish-round bulbs of a beautiful dark red colour. With eye-catching red rimmed flesh and a stronger flavour than most varieties, this RHS AGM variety makes an attractive addition to salads. An excellent cropping red onion with good storage potential. Height: 45cm (18”). Spread: 15cm (6”).


Companion planting: Try growing onions with mint to confuse and deter onion fly.
