It depends on the iris, genus and species. What do you have? and whether it's a hybrid and if is, what kind and where you live. If I recall, you're S.

I've just put the seed in a pot of commercial potting mix and voilà! a new seedling. They take a few years to get to blooming size. Now tell me -- I've grown many irids from seed, but never Iris. I just got some Iris seed -- is there anything special I need to know about germinating Iris?
