Louisiana irises have tall, spiky, green leaves. Established plants produce several flower stems with multiple flowers on each stem. All the Louisiana irises are evergreen and add interest to the pond throughout the year. Supplied bare-rooted.

Top tip: Louisiana irises need room to grow.  The root system expands rapidly in the Spring and after flowering, which is the best time to divide.

Flowers: June/July

Height: 30 – 70cm

Propagation: Louisiana irises produce a woody root system with many offshoots that can readily be separated and grown on.

Depth of water over the soil: 0-10cm

Planting: Plant directly into consistently moist ground, or into a 10lt planting crate using heavy garden loam or Westland Aquatic Soil and position on a shelf in the pond.
