Hi daylilyfanatic4,

Daylily rust is different from the other rusts and normally does not overwinter in your area because it needs green daylily foliage to live or an alternate host; the plant patrinia. So as long as you don't have patrinia somewhere close, or keep your plants protected with green foliage throughout the winter, I would not be concerned about rust.

If you buy plants from an area where rust is endemic, it would be better to get them late in the growing season, and if rust does develop, then winter will kill it for you.

I know Paul Limmer ( on LI) has told me he gets it every year. He brings in plants from FL every year. However, ( much as is the case here) it does not over winter) and when it hits, it is almost always after bloom season - in late August or early-mid September.

I have had daylilies for quite a few years now and have not had any rust problems at all fortunately here.

I also have never (knock on wood) seen rust in my gardens. And I do buy from southern growers.

My personal opinion ... if I ever get rust, I'm not going to worry about it, since it is a foliage issue and will not overwinter in my harsh winter climate.

I did see it a couple of years ago when I went to FLA on the "Mecca" tour ... personally, if I had to spray harsh chemicals to control something like that, I wouldn't grow daylilies. That's my opinion only.

Hi Thanks . I'm glad your were able to identify this for me. Thanks again.

Oops Wrong forum. This was meant for te ferns. Thanks for your help about the rust though.
