Gale, I buy from the auction (do I ever?!) but can't advise on your zone. You are very wise to check with others who share your climate. Good luck and have a ball.

Gale you could try Mike Grossman at Northern Lights Daylily he sells on the Lily Auction as mike144mann he also has a website I don't know the address though you could do a search for it, he doesn't sell off the website I believe but you can at least see what he offers. Northen Lights I believe is in MN so you should have no problem with plants in Zone 5.

Look for plants from northern more hybridizers. Emmerich, Norris, Korth, Mason, Culver to name only a few.

Here is my two cents worth. I have bought a few daylilies from the Lily Auction. First look where they are coming from. I understand southern growers are apt to have the dreaded "rust". You don't want that. I then look how much shipping costs are. I alway try to buy several at a time to save on shipping. I also look at his past record. He/she should have a near 100% approval rating.
I am in Zone 7 North Ga. but pretty close to Zone 6. We get weather no colder than -5. I keep my lilies mulched with mini pine bark. I would buy from any of the states around me, Alabama, TN., Mississippi, but I also buy from further north, Ohio, PA, etc. I bought two from abundadantlilies or something like that and he was great to deal with. When you win answer their email immediately and send your money soon. If you have a PayPal account, that's even better. Good luck. Sarah

I'm in zone 5 too but in Illinois. I have ordered from Solaris Farms in Wisconsin a few times. The prices are good and he sends beautiful plants and nice bonuses. I figure if they grow in Wisconsin they should grow in Illinois and so far so good.
