I want the variegated foliage in with my regular tall bearded in the mixed bed.the color of Pallida's flower would fit right in with the other blue/violets there too. I would like the white margin not the yellow.There is a Jude the Obscure Rose in that bed and think the white would just set it off. I have had difficulty locating an online vendor. Blue J Iris has all, but the Pallida White Zebra is sold out. They do have the Argentea. Anyone know of the pros and cons of the 2? Does anyone know of a different supplier? Thanks,Iris are small in number in my garden but the stars of the spring.
