Iris 'Warleggan' is a type of Tall Bearded Iris that is recognized for its distinct and attractive blooms. The flowers have large, showy petals that come in a blend of colors, usually with a combination of deep blue or violet standards, which are the upright segments of the petal, contrasting with falls that extend downwards, often showcasing a velvety texture with a combination of purples, blues, or even a hint of bronze or gold. The falls might display intricate veining or a splash of lighter or brighter hues towards the center, called the 'beard', which can be a strikingly different color such as white, yellow, or orange, adding to the visual interest of the flower. The beard is plush and serves not only as a focal point but also aids in the pollination process. Iris 'Warleggan' leaves are long, sword-shaped, and bright green, providing a backdrop that highlights the beauty of the blooms. The foliage grows in a fan-like shape, giving structure and formality to the plant's overall appearance, thus making it suitable as a border plant in gardens or as an eye-catching feature in floral arrangements. The bloom season is typically in the late spring to early summer, offering a captivating display that attracts gardeners and pollinators alike.

  • water dropWater

    Tall Bearded Iris, commonly known as Iris 'Warleggan', should be watered deeply to encourage root growth but allowed to dry out between waterings, as they do not like to remain in wet soil. Generally, this means watering once a week, providing about an inch of water each time if there has been no significant rainfall. During hot, dry spells in summer, they may need water twice a week. In the spring and cooler months, reduce the amount of water to prevent waterlogging. Always avoid overhead watering to prevent issues with rot, instead focusing the water at the base of the plant.

  • sunLight

    Tall Bearded Iris, also known as Iris 'Warleggan', thrives in full sun, requiring at least 6 to 8 hours of direct sunlight each day. The ideal spot for this plant is in a location that receives unobstructed sunlight throughout the day, ensuring the rhizomes can dry quickly after rain and dew, preventing rot.

  • thermometerTemperature

    Tall Bearded Iris, known as Iris 'Warleggan', prefers temperate conditions and can tolerate temperatures as low as 14 to -50°F in winter as part of their dormancy period. They can endure high summer temperatures up to 90°F but perform best when nighttime temperatures fall between 55°F and 65°F. To ensure optimal growth and flower production, plant them in an area that experiences a normal fluctuation of seasonal temperatures.

  • scissorsPruning

    Prune Iris 'Warleggan', commonly known as Tall Bearded Iris, to remove deadhead flowers after blooming to encourage new growth and prevent seed formation, which can reduce vigor. Cut back the foliage to a height of about 6 inches after frost has killed the leaves in late fall. This helps to prevent disease and pest problems and tidies the plant for winter. Divide the rhizomes every 3 to 5 years, typically in late summer, to rejuvenate the plant and promote vigorous growth and blooming for the following season.

  • bambooSoil

    Tall Bearded Iris prefers well-drained soil, which can be achieved with a mix of loam, sand, and compost. The ideal pH for the soil should be slightly acidic to neutral, between 6.8 and 7.0. Adequate drainage is crucial to prevent root rot.

  • circleLife cycle

    The life cycle of the 'Warleggan' Tall Bearded Iris (TB) begins when a seed germinates, typically in late summer or autumn. After germination, a seedling grows and develops into a young plant with a rhizome, which is an underground stem that stores nutrients and produces roots and leaves. Over time, the rhizome grows and eventually sends up new shoots that will form the iris's distinctive sword-shaped leaves. The plant reaches maturity and enters the flowering stage in late spring to early summer, showcasing its striking blossoms that can vary in color based on the hybrid variety. After flowering, the plant enters a period of dormancy, especially in regions with hot summers or cold winters. Throughout its lifetime, the rhizome can be divided and replanted to propagate new plants, continuing the cycle.

      Late summer to early fall

    • The Iris 'Warleggan', known commonly as the Tall Bearded Iris, is typically propagated through division, a process best done in late summer after the blooming period has ended. Division involves carefully digging up an established clump of irises and separating the rhizomes—thick, fleshy roots which store nutrients for the plant. Each cut section of the rhizome should have at least one fan of leaves and a portion of roots. Trim the leaves back to about 6 inches (approximately 15 centimeters) to reduce water loss and replant the divisions 12 to 24 inches apart (about 30 to 61 centimeters), positioning the rhizome just at or slightly below the soil surface. This method allows for the plant to establish itself before the onset of winter, ensuring a robust start for the next growing season.
