I have TUSK and last summer it totally died back to one little leaf, and I couldn't stand it so I dug it up and potted it. It really came back to life in the pot, so in another month I plan to replant it in a better spot where the daylilies all seem to do well. And then hopefully it will become like my other favorite spider, FREE WHEELIN', which it will be close to. I also have NORTH WIND DANCER and it dies back because it's a dormant, but each year the plant seems to be getting bigger, so hopefully it will do well this year.
