This cannot be ID for sure as I. suaveolens; I. pumila is also present in the area, but the plants seeds were collected had short stems and sometimes 2(3) flowers/stem. Taking these into consideration together with the collection site, and opinions of others Iris growers, it is offered as I. suaveolens B17Dob.
The collection is marked and when it flowers, if it proves otherwise, the name can be change accordingly.
The flowers can be yellow or purple, large and fragrant. We’ll see. In any case, perfect for the rock garden.

Germination: probably like for I. pumila; fresh seeds should germinate easily, after they get in deeper dormancy may need alternate cycles of cold/warm.
