This is the tall, bearded Iris. She takes her name from her graceful falls. Her standards are upright and elegant. This is a rhizome as opposed to a bulb, that is to say that her roots are large and tuberous spreading out in all directions. She is generally divided every three to five years to contain her growth. It is not a good idea to plant the Iris near roses or any other plant whose water and food supply she might interfere with.
