If that little iris multiplies and you need to find some of it a home you know you have help here. LOL An MDB is harder to pair as it is such an early bloomer I do not have as many other plants blooming at that time. If I could make a suggestion, before you make a decision about the little iris pot it and then when it blooms move the pot about to see what goes with it. Many times an iris from a distance looks better than when viewed up close. Of course, the opposite is true also.
