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.

Shallot 'Jermor' (Autumn Planting)

Allium cepa (Aggregatum Group)

 Customer Rating

Autumn planting.

Shallot 'Jermor' is from French production of Jersey 'half long' types with long, rather than rounded bulbs that are often referred to as 'banana' shallots. The shiny copper-skinned bulbs with crisp, pink-tinged flesh make this a favourite with exhibitors. This RHS AGM variety is equally popular in the kitchen for its superb sweet taste. An excellent variety for autumn planting with good storage potential. Height: 35cm (14"). Spread: 15cm (6").
