  • skullToxicity

    • To humans

      The Tall Bearded Iris, commonly referred to just as Iris, contains compounds that can be toxic if ingested. The rhizomes, which are the underground stems of the Iris, are the parts that pose the most risk. If someone consumes parts of the Iris, particularly the rhizomes, they might experience symptoms such as stomach pain, nausea, vomiting, and diarrhea. Ingesting large amounts could potentially result in more severe health issues, but typically, handling or incidental contact with the plant is not harmful.

    • To pets

      Similar to humans, the Tall Bearded Iris can also be toxic to pets if they ingest the plant, especially the rhizomes. Symptoms of Iris poisoning in pets might include gastrointestinal distress like vomiting, drooling, lethargy, and diarrhea. In severe cases, if a large amount is consumed, it could result in more serious symptoms, and veterinary attention should be sought. As with humans, the toxicity primarily relates to ingestion rather than contact.

  • water dropWater

    Tall Bearded Irises like 'Eileen Louise' need consistent moisture during the growing season, especially when forming buds and blooming. It is best to water deeply but infrequently, providing about an inch of water per week, which equates to 0.6 gallons for an area of 10 square feet. The soil should be allowed to dry out between waterings to prevent rot. During the hottest part of the summer or dry spells, increase watering to twice a week, ensuring the soil is well-drained. Do not water excessively as standing water can lead to diseases.

  • sunLight

    Tall Bearded Iris ‘Eileen Louise’ prefers full sun exposure to thrive. A minimum of six hours of direct sunlight per day is ideal, with more sunlight resulting in better blooms. Place the iris in a spot where it receives unhindered, full sun throughout the day for optimal growth and flowering. Avoid planting it in areas with significant shade, as this can impede its ability to flower and increase susceptibility to diseases.

  • thermometerTemperature

    Tall Bearded Irises are hardy and can tolerate a wide range of temperatures but grow best in conditions that mirror their origins. They can survive winter temperatures down to about -30°F and summer temperatures as high as 90°F. The ideal growing temperature range for the iris is between 55°F and 75°F. Ensure the plant is well-mulched during winter to protect against extreme cold.

  • scissorsPruning

    Tall Bearded Iris 'Eileen Louise' should be pruned to maintain plant health and encourage future blooms. After flowering, remove spent blooms. In late summer or fall, trim back the foliage to about 6 inches above the ground to minimize overwintering pests and diseases. Pruning is also necessary when dividing iris clumps, which should be done every 3 to 5 years. The best time for division and pruning is after the flowering period, typically late summer.

  • circleLife cycle

    Iris 'Eileen Louise' (TB), commonly known as Tall Bearded Iris, begins its life as a rhizome planted just below the soil surface, usually in late summer or autumn. The rhizome grows roots and foliage emerges as sword-shaped leaves in a fan-like formation, preparing the plant for photosynthesis and growth. In the subsequent spring, flowering stalks develop, and between late spring and early summer, the iris blooms, displaying its distinctive large flowers that can range in colors, typically lasting a few days to a week. After flowering, the plant continues to photosynthesize and store energy in the rhizome for the next season. By late summer, the foliage may start to wilt and the plant goes dormant, conserving resources through the winter. The life cycle repeats when the weather warms, with the potential for division and replanting of the rhizomes to propagate new plants every 3 to 4 years, sustaining the spread of the iris in the garden.

      Spring to Summer

    • Propogation: The most popular method of propagating Iris 'Eileen Louise' (Tall Bearded Iris) is by dividing rhizomes. This should be done after the flowering season has finished and the plant has gone dormant, which is typically late summer to early fall. To propagate, carefully dig up the clumps of irises, making sure to minimize damage to the rhizomes and roots. Using a sharp knife, divide the rhizomes by cutting them apart, ensuring that each division has at least one fan of leaves and a portion of roots. Trim the leaves to about a third of their height to reduce water loss and replant the rhizome divisions promptly, placing them so that the top of the rhizome is slightly exposed to the air. Space the new plantings about 12 to 24 inches apart to allow for growth. Water the newly planted rhizomes thoroughly to help establish them.
