Rust Resistance Ratings of My Introductions
Click on any name in the list below to go to the information page for that introduction.
The chart below shows the rust resistance rating system that I used for the duration of my rust resistance screening program, which lasted for five summers - 2012 through 2016. My daylilies have two different evaluation considerations: 1.) Rust Resistance rating and 2.) the number of years the cultivar was tested. For more on my rust resistance testing program, click here.
