Iris 'Queen's Circle' is a striking flower known for its regal appearance and exquisite coloration. The plant features large, ornate blossoms that are a visual treat. Each flower is composed of six lobes: three upright petals known as standards and three downward-curving sepals called falls. The standards are usually a creamy white, enhancing the majestic look of the flower. The falls exhibit a captivating contrast, with a rich, deep blue or purple bordering that fades into a white center, often adorned with a splash or speckling of the darker color near the throat. The velvety texture of the falls adds further depth to their beauty, and each fall has a distinctive, yellow or orange beard that runs down its center, drawing the eye and accentuating the flower's intricate design. These beards are not only ornamental but also serve to attract pollinators. The leaves of the Iris 'Queen's Circle' are sword-shaped, giving the plant a poised and upright posture.

The foliage remains attractive even when the plant is not in bloom, giving structure to the garden setting. Overall, the Iris 'Queen's Circle' is a mesmerizing and dramatic addition to any garden, with its large, showy flowers and contrasting colors making it a focal point wherever it grows.

  • water dropWater

    Tall Bearded Irises like 'Queen's Circle' generally prefer to be kept lightly moist but not saturated. Watering should be done early in the morning, allowing the foliage to dry before nightfall, which helps prevent disease. During the growing season, they should be watered about once a week with approximately 1 inch of water, although this can vary based on climate conditions. In hotter, drier climates, watering may need to be more frequent. Cut back on watering once the bloom period is over, and during winter months, additional water is seldom required unless the weather is unseasonably warm and dry.

  • sunLight

    Bearded Iris 'Queen's Circle' thrives in full sun, which means it requires a minimum of six hours of direct sunlight each day for the best growth and flower production. Plant it in a spot where it will receive uninterrupted sunlight, away from taller plants that might create shade. The light should be bright but ideally with some protection from the intense, late afternoon sun in very hot climates to prevent the flowers from fading.

  • thermometerTemperature

    The Bearded Iris 'Queen's Circle' prefers temperate climates and can typically survive in temperatures ranging from 14°F to 86°F. However, the ideal temperature for vigorous growth and flowering is between 55°F and 75°F. While irises are cold hardy, it's best to provide winter mulch in areas where temperatures might dip below 14°F.

  • scissorsPruning

    Prune Bearded Iris 'Queen's Circle' by removing any dead or diseased foliage as needed to maintain plant health and appearance. After flowering, cut back the flower stems to the base, but leave the foliage in place, as it will continue to gather sunlight and strengthen the rhizome for the next season. Once yearly, usually in late summer, prune the leaves to about 6 inches in a fan shape to rejuvenate the plant and prepare it for winter.

  • circleLife cycle

    The Tall Bearded Iris 'Queen's Circle' begins its life cycle when a seed germinates in late summer or fall, producing a small seedling. The seedling grows into a clump of sword-like leaves during spring, forming underground rhizomes. Over time, the plant enters a vegetative state where it focuses energy on increasing its size and developing a strong root system. In late spring to early summer of the following year, the iris produces its characteristic large, showy flowers which are white with a blue rim around the petals. After flowering, the plant sets seed capsules if pollinated, while the foliage continues to photosynthesize and store energy in the rhizomes for the next year's growth. The iris then enters a period of dormancy in late summer or fall, with the foliage dying back, and the cycle restarts with the next growing season.

    • Propogation time

      Late Summer

    • Propogation: The Iris 'Queen's Circle', commonly known as the Tall Bearded Iris, is typically propagated through division, which is the most popular method for this species. The best time to propagate is late summer to early fall, after the blooming period has finished and the plant has had a chance to build up reserves. The process involves carefully digging up the iris clumps and separating the rhizomes with a clean, sharp knife or spade. Each section should have at least one fan of leaves and a portion of the rhizome. Trim the leaves to about a third of their length, which is usually 4 to 6 inches (about 10 to 15 centimeters), to reduce water loss. Replant the divisions 12 to 24 inches apart (30 to 61 centimeters), ensuring the rhizomes are just below the surface of the soil to prevent rot. Water the new plantings well to settle the soil around the rhizomes and to help them establish.
