Thank you for the helpful information Elm.  The catalog I bought these from just listed it under "Arilbreds" with all the other arilbreds. Too bad it's not fertile...................... It's a VERY interesting iris!    :-)

       'Turkish Topaz' is NOT an arilbred.  When Lloyd Austin used to import species iris, he often imported a lot of I. stolonifera.  He would then select different variants and sometimes name them.  This is one of the variants he selected.  However, it has to be a hybrid of some kind because of its infertility, perhaps a cross between I. stolonifera and I. korolkowii, 2 regelia species.  If so, it is an RH, a regelia hybrid, but not an arilbred.  As for using it as a parent, it is hopelessly sterile.  It neither sets seed nor has fertile pollen.  I. stolonifera and I. hoogiana, both regelia species,  are both tetraploids.  I. korolkowii is a diploid.  RHs from crosses of I. hoogiana X I. stolonifera will be fertile, as will I. stolonifera X I. stolonifera crosses. So there can be fertile RHs, but in the case of 'Turkish Topaz', I'm sorry, but it is not.
