I just re-read your post and you planted iris bulbs, not rhizomes? Are they more roundish or longish like ginger root?
If you planted iris rhizomes, the rhizomes needs to be at the surface or just barely below or you may not get flowers. Iris rhizomes are always at least partially visible.
Bulbous irises need to be planted a bit deeper.
