Miniature Tall Bearded Iris
This American Iris Society class has the strictest classification. The height range is defined as 16" to 27½" with a height of 21 " to 22" preferred. This bearded class is distinguished by daintiness and delicacy. The blooms should be small and carried on slender, wiry, flexuous stems. The MTBs are often called "table iris" because they are well suited for floral arrangements.
