I am with Bonnie on this. The details are an important component to getting a good guess from the peanut gallery that is the ATP iris forum!
Things or info we need to make our educated guess:
Height
Bloom time (early, mid, or late)
PBF
Fragrance
type (SDB, IB, MDB, MTB, BB, TB) blah blah blah {in this case it appears to be either a BB or a TB)
I am with Mary Ann in that this NoID is a SA
This is the type of info that we need to help you narrow the field so you can buy "test" plants to grow next to your NoID!!!
