I grew Iris vartanii ‘Alba’ long ago when it was inexpensive and readily available for several years. This was probably back in the 1960s or 1970s. New bulbs always bloomed, but the plants were frail and did not persist as garden plants. That I even tried it as a garden plant is a good indication of how naïve I was about these plants back then. It was a winter growing plant and the foliage suffered during alternate freezes and thawing.
