Answer: Iris normally bloom in early summer, with a few varieties repeating in late summer if conditions are favorable. These are becoming more popular as more reliable reblooming varieties are developed. Unfortunately, I can not identify the specific iris you saw. However, Burpee may offer some reblooming iris in their catalog each year, or you might look into some of the iris specialty houses such as Cooley's http://www.cooleysgardens.com/ or Shreiners http://www.oregonlink.com/iris/ for a broader selection of specialty iris.
