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 'Hercules' (Spring Planting)
A well named onion, producing large, almost round, well flavoured bulbs with attractive dark golden brown skins. Onion 'Hercules' has been noted for its outstanding performance in RHS assessment trials, winning an RHS Award of Garden Merit. An excellent early or mid season variety that stores well. Height: 45cm (18”). Spread: 15cm (6”).
Companion planting: Try growing onions with mint to confuse and deter onion fly.
