I bought this iris about 4 years ago. Although I usually buy my irises from specialist growers (less chance of their being labeled incorrectly) I saw this in bloom at a garden nursery and **something made me** buy it :o))

It grows to about 13 inches in height and the petals are quite elongated, especially the falls. It's standards are cream and the falls a mixture of green, cream and brown streaks (best I can describe it).

I'm at a complete loss to know what kind of iris it is. I know it isn't a bearded or Siberica, it isn't a Stylosa or Ensata...what is it?? Please, does anyone have any idea??
The name on the label is 'California' (but it could be mislabelled).
Any help is extremely appreciated..........Thanks!!
