context_page_description: Iris fulva, also known as copper iris, is a species in the genus Iris, it is also in the subgenus Limniris and in the series Hexagonae. It is a rhizomatous perennial, endemic to the southern and central United States. It has copper-red to deep red flowers and bright green leaves.
context_section_description: The Louisiana irises generally all have similar cultivation requirements. They need full sunlight (minimum of 6 hours during summer), moist, acidic soils (ph level of 6.5) with a high organic and high fertility content.
  For best flowering, moisture is essential during late autumn, winter and spring times (October to May), when the plant starts to grow new leaves. They can be given a light feed between autumn and spring, if needed.
  It is estimated to be hardy to between USDA Zones 3 to 10.
  It can tolerate frost but will flower poorly in areas with cool summers.
  It can be grown in southern UK, in damp or wet soils.
  They can be grown in most of the United States, New Zealand and Australia.
  They can be used planted by the edges of ponds and pools or they can be planted in the water. But they need the rhizomes to be pinned into the ground to stop them floating away. Also the rhizomes must be covered in gravel to stop fish disturbing the roots. They can also be planted in streams, but not heavy flowing rivers. It can tolerate pools up to 6 inches deep.
  They also can be grown in containers (even in the water or bog garden) but they must be re-potted and divided every year.
  If using a fertilizer, sprinkle around the plant in late January or February, before the plant is in flower.
  New plantings need to be mulched to prevent sun-scalding. Plantings in the water do not need mulching and tend to grow quicker than others.
