This site claims late winter early spring so perhaps it's normal https://www.gardenia.net/plant/iris-j-s-dijt . I have some Iris Katherine Hodgkin, they are dwarf too, they are well developed but don't look close to flowering.
I've got retiulata in flower from bulbs which flowered last year. I know THEY say they don't do well in the second year, but I just didn't get round to empyting/ re-using the pots.
Some of mine are in flower - a very welcome sight, especially the ones returning from last year. I also found yesterday a beautiful Algerian Iris in flower in the back garden which I'm chuffed about.

Knowledge is knowing that a tomato is a fruit.
Wisdom is not putting it in a fruit salad.
All replies appreciated.Must be global warming!!
Still a welcome site tho as this is their 3rd year in the ground and in big pots under shrubs. Never got them to come back in my Belgian garden.
