Sundra ! It looks as if you have some fairly healthy plants, in a well maintained bed, with no weeds ,or grass for competition. I'm betting that next year will see a lot more bloom !
The others have all made some valid comments, so there is little I can add, but, to "restate": at least a half day's sun.....you say you have that. Planting depth "right'......in "heavy" soils (clay), the rhizome should be "partialy exposed', in "lighter" soils (sand), they can be planted an inch under the surface (but no more !), yours look to be about correct, as to depth. It's not unusual for iris to NOT bloom ,the first year after division, and replanting...especially in areas where they are "marginal" i.e. at the limits of their zone range, or, nutrient levels in the soil aren't quite 'correct" for iris (too much nitrogen, soil ph not quite correct, too wet (or too dry) growing conditions, etc. So, my thinking, if they were mine.....I'd expect bloom next year!
