Bearded irises typically take a couple of years to really get going, so you should see lots of blooms next year. I see that short bloom down in the foliage from time to time, and usually that is with blooms the first spring after planting. Sometimes late freezes and other weather issues can cause that too, but it usually isn't a frequent occurrence. Historic varieties are often quite vigorous and trouble free, traits I love about them! They also have a classic, graceful form I find particularly charming.
