I’ve shared this picture before, but this is the section of the flowerbeds that needed to be separated. There are a large number of mostly light blue blossoms, with only about half the blossoms open, so the irises are definitely healthy, however, they are also getting overgrown. This can be seen by how close together the plants are.
Keep in mind that when they were replanted, each iris was about a foot away from the next one. They certainly aren’t that far apart in this picture. It looks like a solid mass of leaves from one end to the other, and the entire three-foot width of the flowerbed. There are also day-lilies in there, but without the day-lilies blooming yet, it is very hard to even see where they are.
