I need some advice on how to start iris from seed. Can anyone help?

In my opinion, that's not the best way to get iris, but it can be done. In nature when the iris produce their seed, they just blow off and land on a bare place in the ground. When the conditions are right, they will germinate. I would plant the seeds just barely covered with soil, water and keep it in a sunny place, just like the conditions that iris like. If they germinate it will be a l-o-n-g time before you get one large enough to bloom.
The best way to get more iris is by division when they send out babies around the mother plant.

"Just put them in seed raising mix and keep them just barely moist. Best put the pot in semi shade, so it doesn't dry out.
"If it is fresh seed they should start to germinate after 6 weeks, if it is old seed it is better to soak it for a few days, changing the water daily.
"If the seed is from bearded irises, then stratifying in the fridge will help you get quicker germination. Put the seed in some damp peat moss, or paper towel, roll up in a sandwich bag or similar, and put in the veggie crisper for a few weeks. You may even have some seed starting to germinate after this time.
"Plant them out into the garden, or larger pots in early Spring, and you will get some bloom on them the following Spring.
"Expect a wide variety of offspring if they are bearded irises, or Louisianians. Even if they look exactly like the parent plant, the will be genetically different, and cannot be given the name of the parent."
