We have a little experience. When we were collecting daylilies from lots of different sources, we found a couple of potted plants at a local nursery and bought them. They looked very good, but in a short time planted in our garden they became infested with rust and it spread all over the garden. I dug the two DL's that started the problem and moved them to an isolated area. I got some spray and treated the beds. A couple of sprayings about a week apart got it all under control. We buy DL's from lots of sources both spring and fall and have never had another problem. Rust does not survive our winters. I have talked to many people in our area and all the daylily collectors have had a similar experience at least one time. We had lots of first year seedlings the year we got rust and the seedlings were no worse than the registered cultivars. Lots of the seedlings were affected very little.
