I did some checking on varieties. Oregon State U has some information online:
[url=https://nwrec.hort.oregonstate.edu/owonion.html]Overwintering Onions, Willamette Valley[/url]
[url=https://nwrec.hort.oregonstate.edu/onionb-e.html]Dry Bulb Onions, Eastern Oregon[/url]
I kind of resent
that there are so many strains available to commercial growers
. They seem to get down to fairly specific regional choices but, I'll tell you what: I think it may have something to do with climate.
Anyway, Arbini & Locati are farms in the Walla Walla valley and "northern Umatilla County" is in Oregon but not all that far away. There isn't much information on Eastern Oregon, btrowe1. Still, I think that your home there on the Hudson isn't really in a valley like the Willamette.
I searched for the eastern Oregon varieties and began to think that I wasn't going to come up with anything but then found Imai Early Yellow onion seed at Kitazawa. In a way, this is kind of unfortunate since I have already
ordered from Kitazawa and received the shipment just a couple of days ago!! [url=https://www.kitazawaseed.com/seed_135-96.html]Kitazawa Seed (click)[/url]
I also found Senshyu Yellow onion seed available to UK gardeners at Suttons. Aren't Suttons seeds also available in Canada??
