Are these flag iris' something to consider after the banks have been established with other plants or do they tend to kill off their neighbors and take completely over?
Half or better of my pond's banks will not be fishable due to the steepness of the banks (and my lack of gumption to weed whack them). I hope to flood these areas with desirable plants even if they get tall and thick. I do not really want submerged plant life at this point to avoid losing surface area of my small pond, but need the emergent and bank dwellers for erosion control and aesthetics.
