Onion seeds — bulb onions and shallots from Allium cepa

Onions are the foundation of the kitchen garden — grow your own from seed and you can pick varieties for flavour, colour and long storage that you'll never find as sets. From globe and red onions to shallots, browse the Allium cepa family within our bulb vegetable range. New to growing? Our vegetable growing guide covers the essentials.

Onions need an early, long season. Sow in late winter for well-sized bulbs — the calendar shows when.

From bulbs to spring onions

Grow full bulb onions and shallots for storing, or quick spring onions for salads in a fraction of the time. Onions are great companions for carrots, and you'll find leeks and the rest of the family together under bulb vegetables and the wider root veg range.

Growing and storing well

Onions like firm, fertile, sunny ground — prepare it with our soil guide — and steady, light feeding (see the feeding guide). Ease off watering as the bulbs swell, then ripen and dry them well; our harvesting and storing guide shows how to keep them for months.

Want onions in weeks, not months? Fast spring onions crop in rows, pots and the gaps between slower veg.

Popular vegetable categories: Allium cepa · Spring Onion · Leek · Bulb Vegetables · Root Vegetables

At SeedsChoice, every order ships from Meppel, NL with fast, tracked EU delivery.

Frequently Asked Questions

Seed or sets — which is better?
Seed gives you far more choice of variety, better flavour and longer storage; sets are quicker and easier but more limited.

When do I sow onions?
Late winter to early spring, as they need a long season to build a good-sized bulb.

Why are my bulbs small?
Usually sown too late, too crowded, or under-fed — start early, thin them and feed lightly.

How do I store onions?
Let them ripen, dry the necks thoroughly, then keep them somewhere cool, dry and airy.

What grows well with onions?
Carrots — grown together they help mask each other from their respective pests.
