Strangely, mine didn't germinate.... not one! I always start my onions and leeks in March, and have never had a problem. This year, the two varieties of onion I started failed to germinate. I have no issue with the leeks however.

great flavor and stored well but have had some issues with germination

I start my seed indoors under lights and no heat in January. Planting them in the garden mid March. They can take the cold like a champ. I've been growing the Spanish Yellow for about 10 years and they always grow to be a perfect sized bulb by mid July. As long as you get your timing right they are excellent performers. They keep until March then I process them to the freezer for further use. They have a lot of flavor without being to harsh.

I started these January and planted out in April. Great Seeds!

I was really pleased with my Utah Yellow sweet onions. They were by far the strongest onion plants. They grew bigger that all my other onions, up to around softball size. I have had good success storing these also. The first year I grew them they stored until spring with minimal quality decline. I will definitely keep growing these.
