Hello! I appreciate your photos and comments. I think I'm dreaming the impossible onion dream, but perhaps you can help: I'm looking for a white, large globe, short-day onion that is a good keeper. I'd prefer open-pollinated, but hybrid is OK. I'm in the Phoenix area, and all my onions are kept in my extra veggie fridge, but I'm concerned about onions that say they only keep for a month or so. Is NuMex Radiance a good choice? I'm also considering White Castle. Thank you for any help!! ~Karen

No it is not. Has about half the keeping qualities of yellow Granex. I can keep them about 3 months without refrigeration. Of course all onions keep pretty well when refrigerated. There is a series of short day onions from New mexico State. You might want to contact them to see if any of their varieties have keeping qualities. In most cases short day onions tend to be sweet, the long day very pungent onions are the storage onions. Radiance is an excellent onion for both production a nd flavor.

I was looking for the same thing last year for my garden in Chandler, AZ and settled on NuMex Casper. I planted seeds 10/15/15, and harvested 6/19/16. So far, it is storing well, at almost the 3 month mark. Technically, it's an intermediate-day variety. I believe it was bred to be seeded February 1 in the Las Cruces area, but the fall seeding worked for me better than the February 1 date. As for taste, it's not the sweetest white onion I've ever tasted, but it's not pungent either, and you can eat it raw with no "breath issues." Overall, I think it's a good compromise between sweetness and storage. Here's what the NE Seed online catalog has to say about Casper: NuMex Casper stores well and is great for production in Mexico. NuMex Casper is an intermediate day white onion that has proven itself over years of commercial use. This jumbo-sized onion variety features attractive round to Grano shaped bulbs with clear white skin and crisp white flesh. Tolerance to Pink Root.

Does anyone know where to get Numex onion seeds anymore? NE Seed (formerly DP Seed) used to carry them, but I can't find them anywhere but Amazon now - and I have been disappointed with seeds from Amazon. I miss my Numex Radiance!

Numex Radiance is an average keeper among short day onions. Note that short day onions are not noted for use as storage onions. Best keeper and an overall good producer I have tried is White Phantom. Numex Radiance does out perform it at harvest time, but I pulled Phantom in May, hung them from rafters in a storage shed, ate the last ones in mid-January. Radiance rarely makes it to Thanksgiving.

I've never purchased seeds from these folks, but here is what I found...
