I don't have my photos on this computer to compare, so might be jumping the gun on this one (the falls look a bit long, but it could be the angle and age of the flower making it look this way); anyway, J1 reminds me a lot of an Iris x germanica cultivar called 'Dorothea'.  There isn't much documentation for this cultivar, but I'm pretty sure my plants are correct and they look very similar in coloration.  It is a largish IB in size (maybe squeaks by as a small TB), and it blooms moderately early with the other I x germanica and the bulk of the IB's.  The irregular white streaks on the falls are typical (and vary from petal to petal and flower to flower - sometimes they are absent).  I'll compare more closely when I get to another computer - as I could be totally wrong.  I might be wrong about 'Dorothea' being I. x germanica too, but I don't think so.  Regardless, it's one of those hand-me down Iris that seems to have been around forever, and that survives everything thrown at it.  There is a lot of it in old gardens in the Albuquerque area, and I've gotten plants from California too.  I expect it's all over the country, and likely all over Europe as well (???).

I have been spending my time the last few days trying to

 keep up with my historical NOID irises that have been blooming.

 Trying to get them identified and getting their photos.

 Two I found are Frank Adams and Indian Chief. Another was 

identified by a very helpful person on HIPS as Moonlight.

4 new ones today and guess that will take up most of my day

 today along with trying to figure out which new historicals 

I would like to get from the HIPS sale coming up if they are

 available.

The 4 for today that I will be working on are attached. Anyone

knowing right off....all help appreciated. I am learning!

The first two are of the same iris. The small flowered on is 29" tall...is it still a TB?

The white is 44" tall and the flower is 7" tall!! I have never

seen such a huge bloom!
