I have it, but it has been a slow grower for me. It bloomed the first year (2010) but then I moved it last year and it really struggled and didn't bloom, but now it seems happy with two nice big fans so I hope it will bloom next spring/summer. Here was a bloom from the one thin scape I had -- and I didn't get the wonderful deep colors here because of our heat, but I still loved it.
Edit: I just checked the description of TUSK on the Trimmers' Water Mill Gardens website, and the only mention of fertility is at the end where it says "some pods" with no mention of pollen.
