I have had this plant going for 30 years, and have planted it in Northern California, and in North Idaho and have had very good luck with it. I put some up in the winter, as small bulblets, and store them under the house and plant them in the spring, and I plant some in the fall and in the spring I have lots of spring green onions. Good luck.

A white version of the red Egyptian topsetting onion. Milder flavor and it does multiply bulbs in ground. It also sets the top bulbils. More prolific than the red, it can produce as many as 20 one inch bulbs per year.
