ToxicityTo humans
The Dwarf Bearded Iris, often just referred to as Bearded Iris, is not generally considered highly toxic to humans. Nevertheless, the rhizomes (underground stems) contain irisin, iridin, or irisine, which can cause gastrointestinal upset if ingested. Symptoms may include nausea, vomiting, abdominal pain, and diarrhea. It is advisable to avoid ingesting any part of the plant, and always to handle plants with caution, especially if you have sensitive skin, as touching them might lead to skin irritation in susceptible individuals.
To pets
The Dwarf Bearded Iris, commonly known just as Bearded Iris, is considered mildly toxic to both cats and dogs. The most toxic part is the rhizome, but all parts of the plant can cause some degree of discomfort if ingested. The symptoms of poisoning in pets can include salivation, vomiting, drooling, lethargy, and diarrhea. In severe cases, ingestion can lead to more serious gastroenteritis and potentially dermatitis. It is important to discourage pets from chewing on or ingesting any part of the plant. If you suspect your pet has eaten Bearded Iris, contact your veterinarian for advice.

WaterDwarf Bearded Iris 'Westar' prefers consistent moisture during the growing season, especially when the plants are setting buds and blooming. Generally, watering once a week with about one to two gallons per plant should suffice, depending on the climate and soil drainage. During hot, dry spells, you might need to water twice a week. It's important not to over-water these irises, as they do not like standing water and it can lead to root rot. After the blooming period, you can reduce watering frequency, allowing the soil to dry out a bit between waterings.
LightDwarf Bearded Iris 'Westar' thrives in full sun, where it can receive at least six hours of direct sunlight daily. The ideal spot would be a south-facing position that is not shaded by trees or larger plants during the day. Adequate sunlight is crucial for the plant to produce vigorous growth and abundant blooms. Partial shade can be tolerated, but it may result in fewer flowers and weaker growth.
TemperatureDwarf Bearded Iris 'Westar' performs best in temperate climates where the temperature ranges from about 35 to 90 degrees Fahrenheit. They can survive brief dips into the high twenties but prolonged exposure to temperatures below this can be harmful. Ideally, daytime temperatures for peak growth and flowering should be between 60 and 75 degrees Fahrenheit. They are hardy plants that can adapt to varying conditions but do not tolerate extreme heat well.
PruningPruning Dwarf Bearded Iris 'Westar' involves removing spent flower stems after blooming to redirect energy into rhizome growth and division. Additionally, trim any damaged or brown leaves throughout the growing season to maintain plant health and reduce the chance of disease. The best time for a thorough clean-up pruning is late summer or early fall, after the blooming has finished and you prepare the plant for winter.
CleaningAs needed
SoilDwarf Bearded Iris 'Westar' prefers well-drained loamy or sandy soil enriched with organic matter. The ideal pH for this plant ranges from 6.8 to 7.0, slightly acidic to neutral.
RepottingDwarf Bearded Iris 'Westar' typically does not require frequent repotting; it should be divided and repotted every 3 to 4 years to prevent overcrowding and to revitalize the soil.

Life cycleThe life of an Iris 'Westar' (SDB), also known as the Standard Dwarf Bearded Iris, begins with seed germination, typically occurring in late spring to early summer, when soil temperatures are warm. Following germination, a seedling develops, eventually forming a small bulb-like structure known as a rhizome, which serves as an energy store and anchoring organ. Over time, the iris grows leaves and establishes a robust root system; during the first year, vegetative growth is prioritized over flowering. In subsequent years, usually by the second year, the plant reaches maturity and begins its reproductive phase, producing distinctive colorful flowers during late spring to early summer, depending on the climate. After blooming, the flowers are pollinated, either by insects or through self-pollination, leading to the development of seeds in a capsule, completing its reproductive cycle. Once the flowering and seed production are completed, the plant goes through a period of dormancy, especially in regions with colder winters, conserving energy in its rhizome for the next growing season.
PropogationPropogation time
Spring to early summer
Propogation: For the Iris 'Westar', which is a type of Standard Dwarf Bearded Iris, the most popular method of propagation is division of the rhizomes. This is typically done after the blooming period in late summer to early fall. When the clumps become crowded, usually every 3-4 years, they should be lifted from the ground using a garden fork. The rhizomes should then be cut apart using a sharp knife, making sure that each division has at least one fan of leaves and a portion of the roots. The leaves should be trimmed to about one-third of their height to reduce water loss. The divisions can be replanted immediately, spacing them about 12 to 24 inches apart (30 to 60 centimeters) and ensuring the top of the rhizome is exposed to sunlight, as burying it too deeply can prevent blooming. This method encourages rejuvenation of the plant and prevents overcrowding, which can lead to reduced flowering.
