Planting & Care

Where to Plant

  • Sunlight: Aim for full sun, which means at least 6 hours of direct light daily, to get the most vibrant flower production. While these Irises tolerate partial shade, you will notice fewer blooms and slightly floppier leaves if they do not get enough light.
  • Soil: These plants thrive in rich, heavy soils that stay consistently moist or even wet. If you have heavy clay that holds water, this Iris will love it; however, if your soil is sandy, you should mix in plenty of compost or peat moss to help retain every drop of moisture.

Watering Requirements

During the first growing season, keep the soil saturated to help the roots settle into their new home. Once established, Southern Blue Flag Iris can handle occasional dry spells, but inconsistent watering usually leads to browned leaf tips and a shorter blooming window. Think of this plant as a "water lover" that prefers its feet to stay damp, so it is perfect for rain gardens or near pond edges.

Pruning Tips

This Iris grows from rhizomes and produces flowers on new growth each spring. After the flowers fade, you can snip off the spent blooms to prevent the plant from wasting energy on seed production. In late autumn or early spring, cut the dead foliage back to about 3 inches above the ground to tidy up the clump and remove any overwintering pests.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring just as the new green spikes begin to poke through the soil. Avoid using high-nitrogen fertilizers late in the summer, as this encourages soft, lush growth that is easily damaged by the first frost. A light layer of organic mulch around the base will also provide a steady stream of nutrients as it breaks down.

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!
