Those are beautiful, Robin. Thanks for correcting my MTB acronymn. I had a brief brain glitch.
When I read the description of them, I decided I must have some:
"What a miniature rose is to a tea rose, Miniature Tall Bearded Iris are to the Tall Bearded Iris class. Once called Table Top Iris, MTB's have many dainty flowers on a slender stem, 16 – 27.5 inches tall. Be sure to plant this small dainty iris close at hand so that you may inspect and enjoy each perfect miniaturized flower."
