It helps germination if the Iris Tenax seeds are soaked overnight in warm water before planting to soften the hard seed coat, and the seeds have to be planted not deeper than 1/8 of inch. It may take a couple of years for Oregon Iris to establish itself before it starts to bloom. In the Northwest, Oregon Iris seeds can be planted directly outdoors in fall for the best result.
