Iris sibirica Concord Crush - Siberian Iris

Iris sibirica 'Concord Crush' is a Siberian Iris that stands out with its magnificent ruffled flowers filled with intense indigo blue petals that appear to be woven from silk. These majestic and infinitely refined blooms appear in spring, towering over a dense tuft of leaves that remains beautiful for long months. Appreciated for their graceful flowers and sculptural foliage, the so-called Siberian irises are vigorous and beautiful plants related to wetlands, unlike their cousins the German irises. They are also very hardy and adaptable irises, which will thrive in good garden soil that remains moist in summer. They are ideal beside water features, as long as the roots are not submerged in winter. They are perfect for romantic, English, and even contemporary style gardens.

Iris sibirica 'Concord Crush' is a rhizomatous and deciduous perennial plant, with a clumping habit from spring onwards. It belongs to the Iridaceae family. It is one of the many cultivars obtained from Iris sibirica, native to central Europe, eastern Europe, and Turkey (but absent from Siberia), and Iris sanguinea found in China, Siberia, Japan, Manchuria, and Korea. 'Concord Crush' will reach approximately 70cm (28in) in height when flowering, 50cm (20in) in height for the foliage, and the clump will spread over approximately 50cm (20in). Its growth rate is moderate, slower than that of German irises. This plant has an elegant upright habit in dense clumps. The foliage consists of long, narrow leaves of a slightly greyish-green. From early May to early June, depending on the region, the flowering stems project above the foliage, bearing solitary flowers with 3 sepals and 3 petals, successively appearing from the top of the stem towards the lower branches. This iris propagates through rhizomes, with its vegetation disappearing in winter.

'Concord Crush' is perfect by the edge of a body of water or a stream, or simply in very moist soil. It is also suitable for any type of garden that never dries out. Its grace perfectly suits romantic gardens, English gardens, and other mixed borders. In moist soil, it can be planted with summer snowflakes, camassias, poet's narcissus, montbretias, crinums, daylilies, astilbes, columbines, pigamons, corydalis, phlox, asters, herbaceous peonies, alchemilla, and more.

Good to know: The wild Siberian iris (Iris sibirica L.) is an endangered and protected species that must be absolutely respected. Horticultural Siberian irises are hybrids obtained from different species in the Sibirica series (I. sanguinea, etc.). Their flowers are larger than those of the wild forms and come in various colours. Several hundred named cultivars are registered.
