Check out tbfinder.com. Also, since most of these are new within the past 3 or 4 years, click on the names to go to the database entries. There you can find the names of the hybridizers for each. Then you can google a hybridizer's name to see which nursery he/she is with.
For instance, Paul Black, who has hybridized several of these, is located at Mid American Iris Gardens. Unfortunately, I don't see his arilbreds currently listed in his online catalog, but I am sure the catalog will be updated with these when the company reopens for the ordering season next spring. To get what you want, place your orders as early as possible in the spring. Some nurseries begin taking orders as early as February, but they should not send them out until July at the earliest.
