Variegated Stinking Iris Iris foetidissima 'Variegata' (v)
ABOUT
Iris foetidissima 'Variegata' commonly known as the Gladwin iris, is distinguished by its striking foliage and colorful fruit. The standout characteristic of the 'Variegata' variety is its variegated leaves, which have a blend of green and creamy yellow or white stripes, adding a vibrant contrast to garden settings. Leaves of the Gladwin iris are long and sword-shaped, arching gracefully from the base of the plant, creating an elegant clump of strap-like foliage. During its blooming season, it produces typically iris shape flowers, but they are often less showy compared to other iris varieties, with subtle shades of purples and sometimes a splash of orange or yellow towards the throat. The flowers are not the main attraction of this plant; instead, it's the bright orange or scarlet seed pods that split open in the fall and winter, offering a splash of color when many other plants have faded. The seeds remain well into the winter, giving the Gladwin iris recurring visual interest beyond its foliage and flowering period. This plant's appearance with its variegated leaves and colorful seeds makes it a unique and decorative choice for year-round garden appeal.

- Plant Symbolism
- Wisdom: The genus name 'Iris' is after the Greek goddess who was the messenger of the gods and the personification of the rainbow. The plant is commonly associated with wisdom, as the goddess was known to link the gods to humanity, denoting a bridge of knowledge.
- Hope: Irises are often seen as a symbol of hope due to their vibrant and flourishing appearance, suggesting the idea of a positive future.
- Faith: People may visually associate the iris with faith due to the plant's prominence in religious art and its sturdiness as a perennial, which can be seen as a metaphor for steadfastness in belief.
- Courage: The iris, with its bold colors and upright posture, can be seen as emblematic of courage, perhaps drawing on its connection to the Greek goddess Iris, who travelled with the speed of the wind from one end of the world to the other, and into the depths of the sea and the underworld.
- Royalty: Historically, the iris has been linked to royalty and noble bearing, particularly the stylized form known as the fleur-de-lis, which has long been a symbol associated with monarchs and heraldry.
- Purity: The iris can also stand for purity, which is represented in its strikingly clean and distinct lines, and the way it stands apart in the garden, helping it take on a character that conveys a sense of innocence or chastity.
- Water
The Stinking Iris, despite its name, is a plant that prefers consistently moist soil, especially during the growing season, but it's also important to ensure the soil drains well to prevent waterlogging. Water the plant deeply once a week with approximately one gallon of water, allowing the soil to dry slightly between waterings. In hotter, drier periods, you might need to water twice a week, while in cooler, wetter conditions, watering might be reduced. Always touch the soil to gauge moisture levels before watering. Over the winter, reduce watering to match the plant's reduced growth and water needs.
- Light
The Stinking Iris thrives best in partial shade to full shade conditions. It is an ideal plant for spots that are too shady for other plants to flourish. It can tolerate some morning sun, but should be shielded from strong afternoon sunlight to prevent leaf burn. The variegated foliage may be enhanced with some dappled sunlight, so positioning it under the canopy of open trees or to the side of a building can provide optimal lighting conditions.
- Temperature
Stinking Iris is fairly tolerant of a wide range of temperatures and can withstand cold down to about 23 degrees Fahrenheit, making it suitable for many temperate regions. However, they grow best in temperatures between 68 and 75 degrees Fahrenheit. During extremely hot weather, they appreciate extra moisture and shade to help maintain cooler soil and air temperatures around the foliage.
- Pruning
The Stinking Iris benefits from pruning to remove spent blooms and to tidy up any damaged or diseased foliage. This can be done after flowering, generally in late summer to early fall. Pruning helps promote better air circulation and can reduce the risk of disease. Occasional thinning of the clumps every few years encourages rejuvenation and more vigorous growth.
- Cleaning
Not needed
- Soil
The Gladdon or Stinking Iris, prefers well-draining soil with a mix of loam, sand, and leaf mold. The soil pH should be slightly acidic to neutral, ranging from 6 to 7. A good soil mix for this plant could include two parts loam, one part sand, and one part leaf mold or compost to maintain fertility and drainage.
- Repotting
The Gladdon should be repotted every 2 to 3 years to refresh the soil and allow space for growth. It does not typically require frequent repotting as it can spread through rhizomes and become firmly established in its current pot.
- Humidity & Misting
The Gladdon thrives in average to high humidity levels. It does not require any special humidity conditions and can adapt to the natural humidity levels found in most temperate outdoor environments.
- Suitable locations
Indoor
Place in bright, indirect light; ensure good air circulation.
Outdoor
Plant in partial shade, shelter from strong winds.
Hardiness zone
7-9 USDA
- Life cycle
The life cycle of the Iris foetidissima 'Variegata', commonly known as Variegated Stinking Iris, starts with seed germination, typically occurring in spring when the temperature and soil conditions are adequate. After germination, the plant enters the vegetative growth phase, where foliage develops, characterized by the distinctive variegated leaves that are striped with yellow and green. During this phase, the rhizomes (underground stems) also spread, enabling the plant to expand vegetatively. The next stage is the flowering phase, which generally occurs between late spring and early summer, producing mauve or purple flowers. After pollination, often by insects, the flowers develop into seed pods, which later open to reveal bright orange seeds in autumn. The plant remains perennial, and with seasonal cycles, it will repeat the flowering and seed-setting phases annually, having periods of dormancy typically in winter when growth slows down or ceases temporarily.
- Propogation
Propogation time
Spring to summer
Iris foetidissima 'Variegata', commonly known as Variegated Stinking Iris, is typically propagated by division. The best time to propagate this plant is in the early fall, after the flowering season has concluded. To propagate by division, the clumps of the iris should be carefully dug up and the rhizomes, which are the horizontal underground stems, should be gently separated by hand or cut with a sharp knife. Each section must have at least one fan of leaves and a portion of the rhizome. These divisions can then be replanted immediately, at the same soil depth they were originally growing, and spaced about 12 to 18 inches (30 to 45 centimeters) apart to allow for growth. The newly planted divisions should be watered thoroughly to help establish them. This method encourages a robust root system and reinvigorates older clumps, stimulating more vigorous growth and flowering.
