Siberian iris 'Rosselline'


The Iris 'Rosselline' is a charming perennial plant known for its striking flowers and attractive foliage. The flowers of this variety have a unique color palette, usually showcasing a harmonious blend of soft pinks and purples that can sometimes give off a warm, almost rose-like hue. At the center of each flower, you might find a delightful contrast with delicate yellow or white markings, which can draw the eye and add dimension. The blooms themselves are composed of several petals arranged in a classic iris form. Some of these petals stand upright, known as standards, while others cascade downwards, referred to as falls. The standards tend to be lighter in color, while the falls often display richer tones and may have a lovely veining or textured appearance that can be quite detailed and intricate. The flowers exude an elegant and sophisticated charm, often seen with a slight ruffling of the petal edges, which adds a touch of grace to the plant's overall look. Below the flowers, this iris has long, sword-like leaves that form dense clumps. These leaves are usually a deep green, providing a beautiful backdrop that makes the vivid colors of the blooms stand out even more. The foliage may have a vertical form and a slightly arching habit, which contributes to the plant's elegant and structured appearance.

  • water dropWater

    Siberian Iris prefers consistent moisture, especially during the growing season. It should be watered deeply once a week, with adjustments made for rainfall, providing about an inch of water each time, which roughly translates to about 0.6 gallons per square yard of soil. During the hot summer months, you may need to water more frequently to maintain moist soil, particularly if the weather is dry. In contrast, reduce watering in the fall as the plant begins to go dormant. Overwatering or allowing the plant to sit in water can lead to root rot, so well-drained soil is essential.

  • sunLight

    Siberian Iris thrives in full sun to partial shade. It performs best when it receives at least six hours of sunlight each day. The ideal spot for this plant is an area that gets morning sun and afternoon shade, or dappled sunlight throughout the day, to protect it from the intense heat of midday sun. Too much shade can lead to fewer blooms and poor growth.

  • thermometerTemperature

    Siberian Iris is hardy and can tolerate a range of temperatures but grows best when the temperature is between 55 and 75 degrees Fahrenheit. It can survive minimum winter temperatures down to -40 degrees Fahrenheit and summer highs up to 90 degrees Fahrenheit. However, prolonged exposure to temperatures outside its comfort range can stress the plant.

  • scissorsPruning

    Pruning or deadheading of the Siberian Iris is not required for bloom but can improve the plant's appearance and prevent self-seeding. Cut back the flower stems to the base after blooming to keep the plant tidy. Additionally, prune away dead or damaged foliage in the spring or fall to promote healthy growth and reduce the chance of disease.

  • circleLife cycle

    Iris 'Rosselline' (Sibirica), commonly referred to as Siberian Iris, begins its life cycle with seed germination, occurring in cooler temperatures after a period of stratification. The seeds develop into seedlings which further mature into clumps of grass-like foliage. Upon reaching maturity, typically in late spring or early summer, the plant produces slender stalks topped with delicate, typically violet or bluish flowers. After flowering, seed pods form and ripen, eventually splitting open to disperse seeds for the next generation. During summer, the foliage continues to provide a backdrop in the garden, before dying back in late autumn as the plant goes dormant during winter. As a perennial, the Siberian Iris re-emerges from its rhizomes each spring to repeat the cycle.

    • Propogation time

      Spring-Early Summer

    • Propogation: The Siberian Iris 'Rosselline' is typically propagated through division, which is best done in late summer after the flowering period or in early fall. This approach involves carefully digging up the clumps of the Siberian Iris and gently separating them into smaller sections, making sure each section has a few healthy fans of leaves and a portion of the roots. These divisions should be replanted promptly, spaced about 18 to 24 inches (approximately 45 to 60 centimeters) apart, in a well-drained soil with ample organic matter. They should be planted so that the tops of the rhizomes are about an inch (2.54 centimeters) below the soil surface. Water the divisions well after planting to settle the soil around the roots and to help with recovery and establishment.
