Irises brimming with elegance with their remarkably large, broad, flat flowers in surprising colors.
The Black Gamecock is an intense dark purple color with a velvety effect, accented with a golden yellow line.
Iris louisiana 'Red Echo' is a warm, deep carmine red.
Iris 'Docteur Favre' is a surprisingly pure blue.
They bloom in early summer, creating a wonderful contrast with other water irises such as the laevigata, versicolor, or pseudacorus, which bloom earlier.
Its foliage, with its upright, slender shape, is an excellent perch for dragonflies. (80 to 90 cm high)
Another interesting thing: it is highly adaptable. It can live as an aquatic plant in water all year round, or in moist or only cool soil (as long as it is watered during the dry season).
It can therefore be easily planted in ponds, on banks, or around ponds or streams.
Another strong point: it doesn't have an invasive behavior.
It is very hardy, withstanding cold temperatures down to -20°C without any problem.

To take good care of it:
Place it in the sun; it likes it that way.
It doesn't like limestone and prefers neutral soil.
Otherwise, there's no problem as long as it's in soil rich enough in organic matter. If you plant it in the ground, plan for a density of 4 plants per m².
If you plant it in a basket pond, we recommend a 15x25x25 basket.

Care:
If the foliage loses its strength and green color during the warm months and after flowering, this may be due to either a lack of water or a lack of nutrition.
For a lack of water: easy solution: watering.
For a lack of nutrition: 2 solutions:
→ fertilizer
→ rejuvenate the rhizomes by dividing them. Each new rhizome must have a few roots and a few leaves for good growth.

A quick word about their origin: They are the result of crosses between wild species growing in Louisiana (in the United States), such as Iris brevicarlis, Iris fulva, and other natural hybrids.
