The tops of the iris stalks that would have had flowers have mysteriously vanished. It looks like someone took pruning shears and cut the stalks. However, this is very unlikely for many reasons.
First I can't think of anyone in my neighborhood who would do that. Most everyone enjoys seeing the flowers in bloom. Second if it were vandalism they would have had to have planned ahead and carried some shears in their pocket. If one were to destroy my flowers, wouldn't it have been easier to just pull out the plants? Third, the cut off tops are nowhere to be seen. My guess is that a deer ate them for dinner one night.
