How do you identify bearded irises?

Answered by James Porterfield

Identifying bearded irises is not a difficult task once you understand the distinguishing characteristics of these beautiful flowers. One of the most prominent features of bearded irises is the thick, bushy “beards” present on each of the falls, which are the lower petals of the blossoms. These beards can vary in color, ranging from white and yellow to orange, pink, and even purple. They often have a velvety texture and add a touch of elegance and uniqueness to the overall appearance of the plant.

In addition to the beards, bearded irises also possess other identifying traits that can help in their recognition. One such characteristic is the presence of upright, sword-like leaves that emerge from the base of the plant. These leaves are typically long, narrow, and slightly arching, adding to the graceful and statuesque nature of bearded irises.

When it comes to the blossoms themselves, bearded irises exhibit a wide array of colors and patterns. The petals, known as standards, are usually held upright and can be solid in color or display intricate patterns and markings. The falls, as mentioned earlier, feature the prominent beards and also come in various hues and patterns. Some bearded irises have contrasting colors on the falls and standards, while others exhibit a more uniform appearance.

To further aid in the identification of bearded irises, the American Iris Society has classified them into six groups for garden judging awards. These groups are based on specific characteristics and help categorize the different varieties of bearded irises. The groups are as follows:

1. Miniature Dwarf Bearded (MDB): These are the smallest bearded irises, typically growing up to 8 inches in height. They bloom early in the season and have proportionally smaller flowers and foliage.

2. Standard Dwarf Bearded (SDB): Slightly taller than the MDB group, SDB irises reach a height of about 8-16 inches. They also bloom early in the season and have larger flowers and foliage compared to the MDB group.

3. Intermediate Bearded (IB): As the name suggests, these bearded irises fall between the dwarf and tall varieties in terms of height, typically ranging from 16-27 inches. They bloom midseason and have larger flowers and foliage than SDB irises.

4. Border Bearded (BB): Border bearded irises are slightly taller than the IB group, reaching heights of 16-27 inches. They also bloom midseason and have larger flowers and foliage, making them a popular choice for garden borders.

5. Miniature Tall Bearded (MTB): MTB irises are taller than the previous groups, growing up to 27 inches in height. They bloom mid to late season and have smaller flowers and foliage compared to the tall bearded irises.

6. Tall Bearded (TB): The tallest group of bearded irises, TB irises can reach heights of 27 inches or more. They bloom late in the season and have larger flowers and foliage, making them a stunning focal point in any garden.

When identifying bearded irises, it's important to consider not only the physical characteristics but also the specific variety or cultivar. Each cultivar may have its own unique traits, such as color variations, fragrance, or ruffled edges, adding to the diversity and allure of bearded irises.

In my personal experience, I have encountered various bearded irises while visiting botanical gardens and attending flower shows. The vibrant colors and intricate patterns of the petals always catch my eye, and the distinctive beards add an extra touch of intrigue and beauty. I find it fascinating to learn about the different groups and classifications of bearded irises, as it allows me to appreciate the diversity and complexity of these stunning flowers.

Identifying bearded irises involves observing their beards, upright leaves, and the colors and patterns of their petals. Familiarizing oneself with the six groups established by the American Iris Society can also be helpful in recognizing the specific characteristics of different varieties. So, next time you come across a bearded iris, take a moment to appreciate its unique features and the beauty it brings to any garden or floral arrangement.
