Well, I'm slowly getting there. When I get around to it, some number of cultivars will get the boot from the garden this year, at least partly due to rust susceptibility.
The problem is that new plants come in, it is not always possible to research parentage, and I am still a sucker for certain characteristics...
But this year I am buying few(er) daylilies, and most of those should have some degree of rust resistance.
In our seedling patches, we can select for rust resistance.
And so it goes...
