About

Iris giganticaerulea, the giant blue iris, or Louisiana Iris, is a species of iris, in the subgenus Limniris, in the series Hexagonae. It is a rhizomatous perennial, from northern America. It has long bright green leaves, very tall stems and one or two musky fragrant flowers in a range of blue shades (pale, bright, dark, lavender and violet) or rarely white.

How to grow it

The Louisiana irises generally all have similar cultivation requirements, with minor differences.

They need full sunlight or partial shade, moist, acidic soils (ph level of 6.5) with a high organic and high fertility content (or humus rich).
