I got a couple of box store daylilies back in the early 90's, before daylily rust was a problem. They're still going strong.
Then when the daylily bug got me this year, before I knew about Lily Auction, etc., I bought some (American brand) in packages from Walmart.
NONE of them have been what was on the package.
Conclusion now is, I will never buy daylilies from box stores again.
