ABOUT

The Iris 'Domino Noir' is an enchanting variety that boasts striking blooms with a unique color combination. Its flowers exhibit rich, velvety dark purple, nearly black shades, which are contrasted by a small patch of white or creamy yellow at the base of the petals. The delicate veining that runs through the petals enhances their sophisticated look. Each flower is comprised of six lobes; three upright petals called "standards" and three downward curving petals known as "falls." The standards are beautifully shaped, adding an architectural element to the flower's silhouette, while the falls are broad and ruffled, lending a lush, full appearance to each blossom. The flowers bloom on tall, sturdy stalks that rise majestically from a clump of sword-shaped, bright green leaves. The leaves themselves provide a vertical element in the garden, with their upright habit and pointed tips. 'Domino Noir' is a feast for the eyes when in bloom, presenting an air of elegance and mystery that makes it a favorite among gardeners and a standout in any floral display where it appears. Additionally, this iris variety may exhibit a subtle fragrance, adding another sensory layer to its already impressive floral show.

Pruning

Water
Tall Bearded Irises, like the Iris 'Domino Noir', have moderate watering needs, generally requiring around 1 inch of water per week, including rainfall. Deep, infrequent watering is best, aiming to encourage deep root growth; therefore, you might water with about 1 gallon per week per plant, applied directly at the base, to minimize wetting the foliage. During the growing season, especially when rainfall fails to meet the plant's needs, additional watering is crucial. Conversely, reduce watering after blooming has finished and during dormancy in the fall to prevent root rot. Always ensure the soil has proper drainage to prevent water from pooling.
Light
Tall Bearded Irises like Iris 'Domino Noir' perform best in full sun conditions, which means they should receive at least 6 hours of direct sunlight each day. Choose a spot in your garden where the plant will get unfiltered sunlight for most of the day; this will help ensure vigorous growth and abundant blooms. Light shade, particularly in the afternoon, is tolerable, but too much shade can lead to poor flowering.
Temperature
Tall Bearded Irises such as Iris 'Domino Noir' prefer temperate climates and can survive in a wide temperature range from 30°F to 90°F, but they thrive best when daytime temperatures are between 68°F and 86°F. They can withstand light frosts, but prolonged extreme cold or heat can be detrimental to the plants. Ensure they're planted in areas that don't experience severe temperature fluctuations.
Pruning
Prune Tall Bearded Irises like Iris 'Domino Noir' to remove spent flowers and trim back foliage after blooming to maintain plant health and aesthetic appeal. Annual pruning should be done by cutting the flower stems down at their base after blooms have finished. Clean up any dead or damaged leaves throughout the season to promote good air circulation. Foliage should be trimmed down to about 6 inches in the late fall to get ready for winter and discourage pest problems.
Cleaning
As needed
Soil
Tall Bearded Iris 'Domino Noir' prefers well-draining soil with a slightly acidic to neutral pH, ranging from 6.5 to 7.0. A soil mix with plenty of organic matter, such as loam augmented with compost and coarse sand, is ideal to facilitate drainage and provide nutrients.
Repotting
Tall Bearded Iris 'Domino Noir' does not require frequent repotting and can be divided every 3 to 5 years. It's best to repot and divide them after blooming, during late summer.
Humidity & Misting
Tall Bearded Iris 'Domino Noir' is tolerant of most humidity levels typical of outdoor garden conditions and does not require specific humidity adjustments.
Suitable locations
- Indoor
  Place in a sunny spot, ensure good airflow and well-draining soil.
- Outdoor
  Ensure full sun exposure and well-draining soil composition.
- Hardiness zone
  3-9 USDA
Life cycle
Iris 'Domino Noir' (Tall Bearded Iris) begins its life cycle as a rhizome, which is a type of bulb-like structure that is planted just below the soil surface. When growth conditions are suitable, typically in early spring, new shoots emerge from the rhizome, developing into long, sword-shaped leaves. As the plant matures, flower stalks called "scapes" grow upward, culminating in the blooming of distinctive black flowers often highlighted with deep purple or maroon shades, usually in late spring to early summer. After pollination, often by insects like bees, the flowers produce dry capsules containing seeds. Once the flowering ends, the foliage continues to photosynthesize and store energy in the rhizome for the following season. The plant then enters a period of dormancy in late autumn or winter, during which the foliage dies back, and the rhizome rests until the next growing season.
Propogation
- Propogation time
  Spring to Summer
- The most popular method of propagating Iris 'Domino Noir', which is a tall bearded iris, is through division of the rhizomes. This process is best done after the flowering period, typically in late summer to early fall. To begin, carefully dig up the iris clumps, maintaining as much of the root system as possible. Once the clump is out of the ground, clean off excess dirt and separate the rhizomes by gently pulling them apart or cutting them with a clean, sharp knife. Each division should have at least one fan of leaves and a portion of healthy rhizome with roots. Trim the leaves to about 6 inches (15 centimeters) to reduce water loss and replant the divisions 12 to 18 inches (30 to 45 centimeters) apart. Water the newly planted rhizomes well to help establish them. This process is a reliable way to both propagate the irises and rejuvenate older plants that have become less vigorous over time.
