Planting and Application:

Black Gamecock is useful in many ways and is best used around ponds, pools, water gardens, Rain Gardens, and for mass plantings. It can also be used in difficult banks and prevent erosion. It makes magnificent cut flowers and is resistant to deer, but pollinators and dragonflies love perching on these tall landing pads! You'll enjoy these dark blooms adding mystery and depth to both the garden border and indoor bouquets.

Create groupings or winding rows throughout your planting beds where they politely spread and fill in all the gaps. The unusual height of these magnificent blooms punctuates the garden bed and border and adds dramatic vertical interest to cottage borders, cut flower gardens and perennial beds!

#ProPlantTips for Care:

Louisiana Iris prefers to be planted in moist, well-drained soil in full sun but will tolerate some afternoon shade, especially in the hotter of its favored USDA growing zones 4 through 9. Tolerant of unseasonable cold as well as heat and humidity, this hardy native is pest and disease free. Planting depth is generally 3 to 5-inches deep and apart, keeping the pointed side up, backfilling with well-draining topsoil, and then watered in well until the ground freezes.

Work a handful of bone meal or slow-release organic fertilizer below the roots, then plant so the top of each rhizome is just an inch or so below the soil surface. You'll see the bumps or shoots of next year's leaves on one side, so be sure to plant with those facing up. The upper 1/3 of the rhizome should be exposed to sunlight. When it gets cold, top with a layer of clean, dry leaves, compost or a few inches of arborist mulch over the rhizome for winter insulation. In spring, pull back the mulch to expose the top one-third of the rhizome once again.

  • Full Sun & Partial/Afternoon Shade
  • Moist to High Moisture Needs
  • Well-Drained Soil of All Kinds
  • Prune
  • Juglone Resistant & Relatively Deer Resistant
