iris 'Superstition'


Iris 'Superstition' is a type of bearded iris known for its dramatic and stunning flowers. It stands out with its velvety deep purple, almost black flowers. Each blossom is composed of two types of petals: the upright petals known as 'standards', and the downward-curving petals called 'falls'. The standards are slightly lighter in color than the falls, creating a beautiful contrast. Adding to the allure, the falls have a slightly ruffled appearance and showcase a striking bright golden or orange “beard” in the center, which is actually a patch of short fuzzy hairs. The bearded iris foliage consists of gray-green, sword-like leaves that grow in a fan-shaped form, and these leaves can add texture and interest to the garden even when the plant is not in bloom. The deep, rich color of the Iris 'Superstition' flowers makes it a favorite among gardeners who want to create a bold visual statement in their landscapes.

As needed
  • water dropWater

    Tall Bearded Iris, commonly known as 'Superstition', requires moderate watering, particularly when the plant is actively growing in spring and leading up to bloom time. It is crucial to avoid overwatering, as this can lead to root rot. The soil should be allowed to dry slightly between waterings. On average, watering once a week with approximately 1 gallon per plant should suffice, depending on the climate and soil conditions. During the hot summer months, you may need to water more frequently, and during the cooler seasons or rainy periods, less often. It is always best to water deeply and less frequently to encourage deep root growth.

  • sunLight

    Tall Bearded Iris 'Superstition' thrives best in full sun conditions. Ideally, the plant should receive at least 6 hours of direct sunlight every day. An area that provides morning sunlight with some afternoon shade can also be suitable, but too much shade may impede flowering. Ensure that the chosen spot is well-lit to promote healthy growth and abundant blooms.

  • thermometerTemperature

    For the Tall Bearded Iris 'Superstition', the ideal growing temperature is between 55°F and 75°F. These irises can survive winter temperatures as low as -20°F but can succumb to frost damage during active growth if temperatures dip below 29°F. During summer, they can tolerate high temperatures up to 90°F without adverse effects, provided they have adequate water and mulch to keep the roots cool.

  • scissorsPruning

    Pruning is essential for maintaining the health and appearance of Tall Bearded Iris 'Superstition'. Deadheading spent blooms prevents the plant from expending energy on seed production. Once the flowering has finished, cut back the flowering stems to the base. Additionally, remove any damaged or diseased foliage as needed. The best time to prune the leaves is in the fall, reducing the foliage to about 4-6 inches to tidy the plant and prevent overwintering pests.

    As needed

  • bambooSoil

    Tall Bearded Irises like Iris 'Superstition' thrive best in well-draining soil with a slightly acidic to neutral pH of 6.5 to 7.0. A good soil mix can be created using loamy garden soil with added sand and compost to ensure good drainage. Avoid heavy, wet soils as these can lead to root rot in irises.

  • plantRepotting

    Tall Bearded Irises such as Iris 'Superstition' typically do not require frequent repotting. They should be divided and repotted every 3 to 4 years to maintain vigor and to prevent overcrowding, which can lead to reduced blooming.

  • circleLife cycle

    Bearded Iris 'Superstition' begins its life as a rhizome, which is a type of underground stem that stores energy for the plant. In early spring, new shoots emerge from the rhizome, growing into tall, blade-like leaves and flowering stalks. By late spring to early summer, the plant blooms with deep purple, almost black flowers that are the namesake for "Superstition." After flowering, the plant enters a period of photosynthesis and energy storage, where it builds up reserves in the rhizome. In late summer or fall, the foliage starts to die back as the plant goes dormant, withdrawing nutrients back into the rhizome for the winter. The cycle restarts the following spring when temperatures rise and the ground warms, prompting the rhizome to produce new growth again.

    • Propogation time

      Late summer

    • Iris 'Superstition', a variety of Tall Bearded Iris, is most commonly propagated through division of its rhizomes. The ideal time for this process is late summer after the flowering has finished, typically in July or August. To propagate, gardeners should carefully dig up the iris clumps and separate the rhizomes with a clean, sharp knife, ensuring each division has at least one fan of leaves. Any dead or damaged material is trimmed, and the leaf fans are often cut back to about 6 inches (15 centimeters) to minimize water loss. The divisions can then be replanted in well-draining soil with exposure to full sun, where they are spaced about 12 to 24 inches (30 to 61 centimeters) apart to provide adequate room for growth.
