I have a large African iris given to me as a gift. I know the African is different from the Bearded, but all the info I could find is for the bearded. I had planned to plant in my bed, but have wood mulch which I read is not good for the African so I am going to create a rock area in the bed to surround the African. I have not worked with iris before and need help in determining if this plant should be divided before planting and then what to do to help it survive and thrive. There appear to be maybe five or six different clumps in the pot. The fans are approx 2.5 feet tall.
