On the Aril Society page about arilbreds, there is a picture of Sky Signal,
which is half hoogiana. It's classified as an OGB+ because the other parent
was a conventional OGB arilbred. It's probably roughly 1/4 TB, 1/4 onco,
and 1/2 regelia. Gives an indication of what hoogiana offspring look like
in terms of form, color, and texture.

On the contrary--it really does show its shape! The falls are oval and very
flaring; the standards are round, lighly ruffled and open but erect. The
aril characteristics (from I. stolonifera ancestry) are the electric blue
flush around the midribs of standards, falls, and style arms, the long
beards, and the flecking. The gold edging is also an aril trait from
stolonifera, different from the superficially similar pattern seen in
bearded irises such as Brown Lasso.
However, your comment hits the nail on the head concerning regeliabreds:
the distinctive traits derived from the oncocyclus species (large round
black signals, intricate veining and dotting, globular form) are simply not
present. And these, for most people, are what it means to be an arilbred.
The flowers of regelias (particularly hoogiana) resemble bearded irises
more than they do oncocyclus irises, in my opinion.
:Do you have any that look like I. korolkowii and might survive here?
In one of nature's cruellest jokes, the most attractive and onco-like
regelia species, I. korolkowii, is a diploid. The other common regelias,
hoogiana and stolonifera, are tetraploids, which means they can produce
fertile amphidiploid offspring (e.g., autosyndetica) when crossed with TBs.
So guess which species most regeliabreds descend from.
There were some korolkowii/bearded hybrids registered and introduced (the
arilbred dwarf FALLEN LEAF comes to mind), but I can't for the life of me
think of any currently available arilbreds with strong korolkowii ancestry
and appearance.
Sharon?
[I. korolkowii is so distinctive that it might be worthwhile to make a
program of crossing it with TBs. Although the offspring would likely be
sterile triploids, some might be attractive and gardenable enough to be
worth keeping.]
