5 Varieties of Long Day Onions

Walla Walla onions

In southern regions of the country, onions are grown in the winter and early spring, when the days are shorter.
Here in the north we plant onions in the spring and grow them throughout the long days of summer.

It is important to choose the right type of onion for the area you grow in.
Here are varieties we have grown.

Next year we will add to this list as we try a few more varieties. If you have a favorite, let us know so we can make it a point to plant them. Thanks!

Note that DTM stands for days to maturity and that will vary with the weather.
The storage time listed is optimal, and may also vary.

Name Color Storage DTM Notes
Sterling white 6 months 95 mild flavor
Copra yellow 1 year 110 smaller than most
Walla Walla yellow 1 month 90 Great flavor
Red Zeppelin dark red 6 months 100 Our favorite red so far.
Ailsa Craig yellow 1 month 95 days huge!

    In So Cal, we plant in the fall and winter for most of our onions and garlic. Green onions, however, we grow year round. One of our short day favs is Red Burgundy.
