I started some last year from seed inside about February and planted them out as soon as I could. Some did well, yield was low. I did like them for cooking and will try them again next year. I tried to fall seed them also and that did not work here in NJ. With my other onions I ways fall seed some and also start some inside in late winter for transplanting.

I'm growing some Red Marble Cipollini for the first time this year. I started from seed on New Years day like I did with my Pontiac onions. These are borderline intermediate day/long day (38-55 degrees). So far they are doing pretty well I think. I planted them with about 2" spacing because they are supposed to be pretty small.

I liked Red Marble last year, and you can pull them at different sizes.

OP, do you know if you are short, long, or intermediate day? I've tried some long day seeds in the spring, and some intermediate seeds, which you can start late fall and overwinter. I find it hit or miss overwintering the plants from seed. I want to buy plants but usually only find long day cippolinis (Borettana) . Just saw some intermediate Bianca Di Maggio plants at Hirt's I'm going to try next year. They are on sale right now!

Here is an oldthread with descriptions varieties.

We can do intermediate and long day, for the most part.

I'm looking for a link I shared a few years ago, i think from The Gardener's Table, about onions and intermediate zones. In the meantime, I like this one. Growing onions. Or maybe it was Golden Gate Gardening.

I have been very successful planting them from seed here in WI. It's been a few years now since I have grown them, and saw them at Jungs as plants, so trying the plant option this year.

I just noticed Walmarts is selling the plants for Hirt's!
