iris 'Comme un Oeuf'


Iris 'Comme un Oeuf' is a captivating and ornamental flowering plant that boasts a delightful visual appeal. Characterized by their striking flowers, these irises exhibit classic flower shapes with three upright petals known as 'standards' and three outer petals called 'falls' that gracefully droop downwards. The color of the blooms is particularly charming, typically presenting a pale to creamy yellow hue that may remind one of the gentle color of an eggshell, hence the name 'Comme un Oeuf' which translates to 'Like an Egg.' The flowers have a silky, almost luminous texture with a subtle, inviting fragrance. The foliage of this iris is equally elegant, consisting of long, slender, sword-shaped leaves that emerge from the base of the plant, forming dense clumps. The leaves are a rich, vibrant green and have a vertical, upright habit that adds architectural interest to the garden. In its full glory during the blooming season, Iris 'Comme un Oeuf' creates an eye-catching display, marrying the softness of its petal hues with the bold form of its leaves. While the blooms are the main attraction, the green foliage remains a beautiful backdrop throughout the growing season, making this plant a valuable addition to any garden for its overall structure and color contrast.

As needed
  • water dropWater

    Tall Bearded Irises, including the variety 'Comme un Oeuf,' generally require moderate watering, especially during the growing season. Ensure the soil is well-drained as these plants do not like to sit in water. Water deeply to encourage root growth, approximately one inch of water per week, either from rainfall or supplemental watering. During hot, dry spells, you may need to water twice a week, but always check the soil moisture first to prevent overwatering. During the dormant season, reduce watering significantly, as too much moisture can cause the rhizomes to rot.

  • sunLight

    Tall Bearded Irises, like 'Comme un Oeuf,' thrive in full sun for optimal growth and bloom. Plant them in a location that receives at least six hours of direct sunlight daily. However, in extremely hot climates, they can benefit from light afternoon shade to protect the blooms from intense heat.

  • thermometerTemperature

    Tall Bearded Irises, such as 'Comme un Oeuf,' prefer temperate climates and can generally tolerate temperatures as low as 5°F in the winter and can endure summer temperatures well into the 90s°F. They perform best with a spring and fall temperature range between 35°F and 70°F, which promotes healthy growth and flowering. It is vital to provide good drainage to prevent rhizome rot during colder, wetter periods.

  • scissorsPruning

    Tall Bearded Irises, such as 'Comme un Oeuf,' should be pruned or deadheaded by removing spent blooms to encourage further flowering and to maintain plant appearance. After blooming, cut flower stalks down to the base to divert energy back to the rhizome for next year's blooms. In late summer or fall, trim back leaves to about six inches in a fan shape to tidy the plant and reduce damage from winter weather.

    As needed

  • bambooSoil

    The ideal soil mix for the Tall Bearded Iris (Iris 'Comme un Oeuf') should be well-draining and slightly acidic to neutral, with a pH ranging from 6.5 to 7. A good mixture could be equal parts of loamy garden soil, peat moss, and coarse sand or perlite to ensure proper drainage.

  • plantRepotting

    Tall Bearded Irises, like Iris 'Comme un Oeuf', generally do not need frequent repotting. They should be divided and replanted about every 3 to 5 years to rejuvenate the plant and prevent overcrowding, which can lead to fewer blooms.

  • water dropsHumidity & Misting

    Tall Bearded Iris (Iris 'Comme un Oeuf') prefers moderate humidity levels. Although they are tolerant of varying environmental conditions, they perform best when humidity is not excessively high, which can promote disease.

  • circleLife cycle

    The life of Iris 'Comme un Oeuf', also known as Tall Bearded Iris, begins with seed germination, where the plant initially develops roots and shoots under optimal conditions of moisture and temperature. The plant then enters a vegetative growth stage where it forms a network of rhizomes and leaves, gaining the energy required to grow and mature. During the flowering stage, the Tall Bearded Iris produces its distinctive large and often colorful flowers, which attract pollinators such as insects and birds. After pollination, the flowers produce seeds that are dispersed to give rise to new plants, completing the reproductive cycle. If conditions are not suitable for seed production, the iris can also propagate vegetatively through the division of its rhizomes. As perennial plants, they enter a period of dormancy in response to colder temperatures during the winter months, re-emerging to begin the cycle anew in the spring.

    • Propogation time

      Late Summer to Early Fall

    • Propogation: The Iris 'Comme un Oeuf', a Tall Bearded Iris variety, propagates most effectively through division, which is typically done in late summer after the blooming period has ended. This allows the plant enough time to establish before the onset of cold weather. To propagate by division, carefully dig up the clump of irises, preserving as much of the root system as possible. Then, using a sharp knife, divide the rhizomes, ensuring each division has at least one fan of leaves and a portion of the roots. Trimming the leaves to a length of about 6 inches (15 centimeters) before replanting helps to reduce water loss and makes handling easier. The divided rhizomes should then be replanted at soil level, spaced about 12 to 24 inches (30 to 60 centimeters) apart to allow for adequate growth. This simple process is highly effective in increasing your stock of irises and maintaining plant vigor.
