My Iris have been in the ground for two years, have healthy leaves but never bloom. What do you think the problem is?

If the rhizomes you planted where small, they may need to mature a bit before they will produce. When planting, place the rhizome just below the soil surface and barely cover with soil. They should be in a sunny spot and receive regular watering so they'll form roots. You can fertilize as soon as leaves begin to show. Use a 5-10-5 formulation. If they don't bloom this year, dig them up and replant them, making sure they're not planted too deeply.
