Concord Crush Siberian Iris

Availability: Out of stock

Concord Crush Siberian Iris (Iris sibirica 'Concord Crush') is a type of beard-less Iris, lacking the fuzzy ‘beards’ of their cousins, however, these are just as elegant! Concord Crush does have incredible double layered blue and royal purple petals with pale-gold highlights, an extended bloom time and have improved pest and disease resistance!

Siberian Iris form long, slender and elegant green blades of leaves that remain lovely all growing season! The foliage waves in the wind and lends vertical texture to the landscape. Concord Crush features a double layer of ‘flags’ and they’re ruffled and curled instead of upright, while the ‘falls’ have a golden accent.

Concord Crush forms 2 foot wide and tall clumps that readily tuck into any existing garden layout or container with ease! Bees and butterflies will be frequent visitors all summer and you’ll have enough blooms to include some in your floral bouquets indoors too!

Planting and Application:

Concord Crush will look lovely around pond edges and meditation gardens, where the large blooms, dramatic color and waving motion soothe the senses. Try installing a Rain Garden in that soggy patch of the yard, or create a garden around where the gutters drain! Add to perennial and cottage borders, or as edging along a path or walkway!

Siberian Iris are very easy-care and low-maintenance, so don’t be afraid to plant these vibrant blooms and ornamental grassy-blades en masse and in large banks for erosion control, to fill large areas, or just wind through a moist garden bed. Pot them up in a planter or container for vertical thrillers and accents!

  • Double Ruffled Blue/Purple Blooms
  • Slender Vertical Green Blades
  • Loves Moist Soil
  • Ornamental Grass Substitute

  • Prune Dead Leaves After Frost
  • Deer, Pest & Disease Resistant
  • Cold & Heat Hardy Zones 3 - 9
