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! :-)

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.
