Allium cepa (aggregatum group) (100 days) Open-pollinated. Longtime Montana farmer and plant breeder Judy Owsowitz loved the hybrid shallot Prisma for its beauty, taste and long storage. So when she heard it was to be discontinued, she pursued her passion, selecting for those traits from the seed that was still available. Six years later she came up with the stunning Glacier Rose, named for its rosy color and the sight of Glacier National Park from her farm. The large 3" bulbs, mostly doubles, retain the parent’s good flavor and, like Prisma, store until the next year’s crop comes in. Despite global warming, this Glacier is here to stay.

The sweetest and mildest member of the onion family, important in Asian, Persian and French cuisines.
Culture: Start indoors in Feb. or March and transplant out in spring almost as soon as the ground can be worked. Set 4–6" apart in trenches in well-dug beds with generous quantities of organic matter. Avoid transplanting next to grass strips; slugs love to dine on tiny allium seedlings. Irrigate seedlings whenever the topsoil dries out.
Alliums
Culture: Start allium seeds indoors in February or March. Minimum germination soil temperature 45°; optimal range 60-70 °. We discourage using bottom heat because alliums germinate poorly in soil temps above 70°. Transplant in spring soon after the ground can be worked.
Alliums are heavy feeders and want generous amounts of organic matter, fertilizer and water. Late transplanting and poor fertility can result in small onions or failure to form bulbs. Alliums are notoriously intolerant of weeds. Slugs love to munch them, and in areas above 40° latitude, root maggots may be a problem.
About allium seed: Allium seed is short-lived. We do not hold over hybrid onion seed because of precipitous decreases in germination. Test 1-year-old seed before using. Discard anything older.
Diseases: DM Downy Mildew PR Pink Root
ALERT: Leek Moth is emerging as a serious pest potentially affecting all Alliums in the Northeast. Consult your local Cooperative Extension for more info.
