Not your typical Iris, the unique native flowering perennial, Copper Iris (Iris fulva) features showy coppery red to orange petals! Not only is the color unique, but the open drooping petals and spreading sepals really set this Iris apart from the rest! Each petal has a dab of gold, and the hue of these flowers can vary slightly because of their native diversity, but we guarantee each will be stunning!

Your bouquets and visiting pollinators will adore them nonetheless! These amazing blooms stand tall atop slender stems and rise over the clumps of sword-like green leaves. Waving like coppery wands for all to see, 2-3 feet in height and spreading 1-2 feet wide.

Like landing pads for beneficial insects and butterflies, even an odd Hummingbird may arrive to sip the nectar, these slightly fragrant flowers are short lived, but there are multiple buds per stem. Profusely flowering for about 3 - 4 weeks throughout April to June. Native Copper Iris are hardy and adaptable native herbaceous flowering perennials that can be found throughout USDA growing zones 5 to 9.

Planting and Application:

Southern Blue Flag Iris are fantastic in any garden location that is sunny and moist to high moisture throughout the year. Plant Native Iris in Rain Gardens and those soggy locations around your yard, like where the gutters drain or the edges of a water feature or pond! Plant in pollinator borders, by the HVAC unit drain, or in the moist mixed perennial and Cottage Garden where all can benefit from the nectar and pollen resource

Water-loving Irises can be planted on banks to prevent erosion, or en masse throughout the sun garden because they are naturally clump-forming and create tidy drifts on their own. The clumps will grow together and block weeds, spreading by rhizomes, so if planted this year, it will be even bigger and better in a season or two! They make magnificent cut flowers and will fill bouquets with vivid blooms!

  • Royal Purplish-Blue Blooms With White & Yellow Accents
  • Upright Spreading Clumps of Green Sword-Like Foliage
  • Slight Fragrance & Vital Pollinator Resource
  • Native Wetland Wildflower
  • Water Features & Ponds, Erosion Control & En Masse Color

#ProPlantTips for Care:

Iris are very easy to grow and easy to plant too! Plant in a full sun location in the cooler regions of their favored growing zones and in planting sites that are high moisture. In warmer areas and drier sites, choose a slightly partially shaded or afternoon shade location.

Any well-drained rich soil works great and Iris appreciates a 3-4 inch thick layer of arborist mulch to keep moisture in better and enrich the soil. Iris rhizomes tend to be close to the surface, so mulch helps protect their crowns from freezes. Deadhead flowers as soon as they fade, and cut back the leaves to the ground after frost kills the tops back in the autumn.

  • Full Sun to Dappled/Partial/Afternoon Shade
  • High to Average Moisture Needs - Native Wetland Plant
  • Any Well-Drained Enriched Soil
  • Deadhead After Bloom & Prune Back After Frost
  • Deer Don't Favor This Perennial!
