Beginner Gardening: Something Growing with Irises, 1 by poinget

Thank you so much for the quick replies. I did plant them all together. These rhizomes came from a single bulbous mass. At the time, I didn't know anything about irises and tried my best not to break up the huge clump too much. Now I have a bunch of baby irises growing closely together and those new unknown plants. These irises are over 40 years old. I have several large beds that consist of one large tuberous mass that I still have to break up (3'x3',5'x5', etc), but I don't have the energy to do it this year, nor the space to replant them (that will change next year). Do you think these were two types of plants that became entangled? All my irises are one type.

About the new irises growing closely together, should I wait till next year to move them? They are only 3-5 inches tall right now.
