Adventitious growths like this aren't too unusual in the plant world generally, but I must say I haven't seen this happen yet on my 30 spuria patches. Looks like you have a plant that is trying to give itself away to the neighbors!
I have seen this happen in orchids, and have even seen new plants sprout from their roots (not rhizomatic roots, but feeder roots), so I would think that new plants could sprout whereever there are viable meristems.

I have never seen this on a spuria iris before.  Out of the old spent bloom stalk is growing a new rhizome, complete with a root about at least an inch long.  This is only one of 3 different plants this has happened to. 
I know that various century plants and onions do this, and the walking iris also is known for this, but it usually happens where there was a flower, as opposed to right off the side of a bloom stalk. 
Is this normal for spuria iris to do this? Does this happen with other irises? 
I've included a few photos, one with the flash on and two without...from both sides of the plant.
