Types of Bearded Irises

Miniature Dwarf Bearded (MDB)

The smallest and the earliest blooming of the Bearded Irises starting late April or very early May. Up to 25cm (8 inches) tall, they make good rock garden and border plants. The stems are usually unbranched with small, dainty flowers that are 4 to 71/2cm (1.6 to 3.0 inches) wide in proportion to the overall plant. Top award is the Caparne–Welch Medal (CW).

Standard Dwarf Bearded (SDB)

These Irises grow 20 to 38 cm (8 to 15 inches) tall and bloom in Southern Ontatio from early May to early June. The stems are branched or unbranched, usually with 2 or more terminal buds and blooms that are 5 to 10 cm (2 to 4 inches) wide. The leaves are erect and no taller than the bloom stalk. The blooming season follows the MDB and ends before the peak of the Intermediates. They quickly create generous clumps and have a wide range of colours.often not seen in other types. They do well in borders and rock gardens and tolerate shade better then the taller plants. Top award is the Cook Douglas Medal (CD).

Intermediate Bearded (IB)

These Irises are 41 to 70 cm (16 to 28 inches) tall and fit between the SDB and TB both in height and bloom time. They bloom in Southern Ontario from mid-May to mid-June. They do well at the front of an Iris bed and start the season early. Top Award is the Han and Jacob Sass medal (SM). The substantially erect stalks are branched and extend above the foliage to display the blossoms without interference. The blooms are 9 to 13 cm (3.5 to 5.0 inches) wide.

Miniature Tall Bearded (MTB)

Charming and dainty with thin graceful stems and small delicate flowers. they are 16-25” tall, (41- 63cm) tall with blooms starting mid to late May. They are also referred to as Table Iris due to their effectiveness in table arrangements. Top award is the Williamson-White medal (WW). The stems are slender and wiry holding blooms not more than 15 cm (6 inches) wide combined height and width. A pleasing fragrance is especially important since they are used as cut flowers.

Border Bearded (BB)

These Irises are shorter than the tall bearded at 40 to 68 cm (16 to 27 inches) but typically bloom at the same time. They display well at the front of the bed and because of their reduced height are more resistant to wind and rain damage making them ideal for areas exposed to the wind. Top award is the Knowlton medal (KM). The stems are erect and branched with flowers no more than 13 cm (5 inches) wide or 22 cm (8.5 inches) combined height and width. The blooms resemble TB’s except the flower size is proportionately smaller to match height.

Tall Bearded (TB)

These are the Iris most envisioned by gardeners and artist alike. They are the showy climax of the bearded Iris season and are 68 cm (27 inches) and over in height. They bloom in Southern Ontario from late May to late June. Top award is the John Wister medal (JW).
