How sweet you are, Marilyn. I do like Tarhelm but probably should stake it long before it blooms. It's upsetting to see it lying down on the earth and soil looks so awful on a white JI.
That garden, the Japanese iris garden at the courtyard, is either "oodles of irises" or havoc. There are many that have to be divided this year and that's a big job. They're all all too close for comfort and many times for identification.
