Red Winter Onion Set

Red Winter Onion Seeds

[120 days] An overwintering onion with pinkish-red skin. The bulbs are good-sized and are ready for harvest a full month earlier than spring-planted sets. The flavour is a bit stronger than yellow onions (which is a good thing for us onion lovers) and they have a longer storage life than yellow onions too.

They’re also amazing storers, lasting from 6-9 months when set up properly. Unlike other over wintering onions, Red winter is best planted between Mid September and Late October or as the climate changes as the soil temperature beings to drop. 

Heavy yielding and delicious raw or cooked.

These onion sets are delivered from late September - November.
