Siberian Iris Concord Crush

Siberian Iris 'Concord Crush' (Iris sibirica 'Concord Crush') is a stunning clump-forming perennial, renowned for its elegant, double violet-blue flowers, which make a sophisticated statement in the garden. The large blossoms are adorned with beautifully ruffled petals, adding texture and depth to the soft violet-blue hue. Each bloom is further enhanced by vibrant yellow signals at the centre of the falls, creating a striking contrast against the rich colours of the petals.

Blooming in late spring to early summer, 'Concord Crush' adds a touch of refinement and colour to borders, mixed plantings, or waterside gardens. The flowers rise gracefully atop sturdy, upright stems, standing proudly above the slender, blue-green foliage. The foliage itself is narrow and sword-like, offering architectural interest and remaining attractive long after the blooms have faded. Easy to grow and relatively low-maintenance, this variety thrives in moist, well-drained soils and tolerates partial shade, making it a versatile addition to a variety of garden styles.
