Slightly trickier, you have to get the timing right. If you plant too early then the onions will be too big by the time winter comes , so the next year they will shoot straight to flower instead of making a bulb. If you plant too late they won’t be big enough to survive the winter. In most of the UK the correct date is about August 18th.
‘Augusta’ -OVERWINTERING or EARLY SOWING
A special large yellow cold-tolerant onion for overwinter growing: Sow late August for large bulbs the next year, or sow in spring to get baby bulb onions to use fresh. (Do half your packet each way.)
For full-size onions: Sow it around Aug 18th in a closely-spaced row. At the start of October they will be a decent size and you just transplant them out to their final position spaced about 15cm apart. As soon as the weather improves in spring they'll be off and away, giving you early large yellow onions. For baby green bulbing onions: Sow in late spring about 3 months later you'll get baby yellow onions , use the whole thing (bulb and greens) chopped in salads or cooking.

Early Pompeii White OVERWINTERING or EARLY SOWING
This smaller but cold-hardy onion is a good variety for overwintering, giving nice white onions in Spring when they are most appreciated. Not huge, but very cold hardy, and quite early.
Alternatively sow in spring to get small white bulb onions to use fresh, so you can do half your packet each way.
For full-size onions:
Sow it around Aug 18th in a closely-spaced row. At the start of October they will be a decent size and you just transplant them out to their final position spaced about 15cm apart. As soon as the weather improves in spring they'll be off and away, giving you earlier onions than you would get otherwise.
For white bunching onions:
Sow in late spring and about 3 months later you'll get small white bulb onions with a long green top, use the whole thing (bulb and greens) chopped in salads or cooking.
Not a storage onion, this is one for eating fresh as and when you harvest it.
