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.

Great quality seeds with high germination rate just a week after planting

I planted the Utah Yellow Sweet Spanish onion seeds on 11/27 and they are only now beginning to sprout. The cipollini onion seeds, planted on the same day, have yet to sprout. I live in the Central Valley of California.
