Description
Iris 'Rose de Perse' is a charming and colourful variety of Bearded Iris. Around mid-May, it produces large, strikingly architectural flowers on long stems that showcase them beautifully above the glaucous green foliage. The predominantly pink corollas are enhanced by a deep purple-violet border on the sepals, along with a stunning coral-red beard. Easy to grow in most well-drained soils, this Iris thrives in full sun, whether in a flower bed or a large rock garden.
Iris lends its name to the Iridaceae family, which includes many other ornamental genera, primarily perennial plants with bulbs, corms, or rhizomes, such as the magnificent Crocosmias. While the Iris genus was discovered in Egypt nearly 3000 years BCE, Iris germanica originates from Syria. It is considered the ancestor of our modern Bearded Irises, called Bearded Irises due to the hairy appendices on the surface of the sepals.
Iris 'Rose de Perse' is a creation by the French breeder Cayeux, a nursery specialising since the late 21st century and based in the Loiret region. Its parent varieties are also two Cayeux cultivars: 'Chevalier de Malte' and 'Poésie'.
A beautiful synthesis of its parents, 'Rose de Perse' is a medium-sized Iris, reaching 85 cm in height and forming clumps 45 cm wide. Its sword-shaped leaves are slightly glaucous green and overlapping at the base, forming graceful fan-like arrangements. In spring, the clump produces highly branched flowering stems, bearing up to nine flower buds. These open around mid-May (earlier in warm climates and later in colder regions). The corollas consist of three upright petals, concealing the three-branched style (the female sexual part), and three horizontally inserted sepals that trail gracefully at the tips. The six floral segments feature an elegant wavy margin, worthy of a haute couture designer. The petals are monochromatic, in a romantic soft apricot-pink hue. The sepals are veined with the same slightly paler pink, blending into a deep purple-violet border that creates a striking contrast. The beard at the base of the sepal is coral-red with a hint of orange. The large flowers measure up to 12-13 cm, blooming for about three weeks until June, and emit a delicate, pleasant fragrance.
Iris 'Rose de Perse' will delight Iris enthusiasts with its generous, romantic-style flowering. Pair it with early-flowering varieties to extend the blooming season. However, it’s wise not to limit yourself to Irises alone, as while their flowers are stunning, their post-flowering appearance isn’t particularly ornamental... Combine them with other plants that will divert attention from their faded summer look. Gauras, with their airy, delicate flowers and long summer bloom, are perfect for taking over. Evening Primroses, with their bright pink or yellow flowers, depending on the variety, will be equally suited to this role, as will charming Daylilies with their star-shaped blooms.

Do you have a very sunny spot, rather dry in summer?
This is the ideal location for planting irises! In shade, they will grow but not flower. They can be cultivated in all regions. Being hardy, they don't require winter protection. Well-drained soil suits them perfectly, even if it's rather dry and chalky or stony. Overly moist soil encourages rhizome rot. Plant from July to September. This gives the rhizomes enough time to grow sufficiently before lifting, then to develop new roots before winter. They should be planted immediately after purchase for best results. Plan to divide irises approximately every four years to provide them with fresh soil, and because clumps thin out from the centre over time. Divide in summer during the dormant period by lifting clumps with a garden fork and selecting the finest rhizomes (discard the smaller ones).
Irises have vigorous growth and require space to develop and flower well. They should be planted with spacing appropriate to the size and vigour of the variety: approximately 45 cm for this Iris 'Rose de Perse' (about 6 plants per square metre). Always consider the direction of rhizome growth by arranging them in a star shape, with buds and leaves facing outwards, and spacing them well away from other varieties so they have room to develop.
Planting
Dig a hole wide and deep enough. Make a conical mound of soil in it on which to place the rhizome with the roots spread out. Cover the roots. It's important that the rhizome sits flush with the soil surface. It must not be planted in a depression (risk of rot). Allow for soil settling and the iris sinking deeper. In clay or moist ground, the rhizome can even be raised on a slight mound a few centimetres high. To help soil cling to the roots, lightly firm the soil and water generously immediately after planting. Water if needed 2-3 times until established.
Care:
Keep the soil weed-free by shallow hoeing, taking care not to damage rhizomes or roots. Weeds shade the irises, retain moisture (causing rot) and attract slugs. Similarly, remove dry leaves. If diseased (with reddish-edged spots from leaf spot disease), we recommend burning them. Remove faded flowers to prevent the iris wasting energy on fruit production.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
