Continuous Blooming Bearded Irises [2 Attachments]

---

I have a question for the bearded Iris enthusiasts. Are there continuous blooming bearded irises out there? I ask this because I have a tall bearded Iris that continues to sent up new blooming flower stalks. It started doing this in late spring and has recently sent up another with a total of five over this time period. This is its first year of bloom. I am also wondering if I should now cut off any existing flower stalks as the last one is about half bloomed and the new one is just coming on.
