This is one of the most famous of the Louisiana irises, a great group of native North American wildflowers. Among the hybrids made from the five native species, Sinfonietta is famous for rich blue blooms with bright golden flashes on blooms up to 6 across.
The Louisiana Irises are some of the most wonderful native plants in North America. Growing in and near wetlands in Louisiana and neighboring states, these amazing irises have cross-hybridized naturally over the years, so there are now an infinite number of colors and types. According to Iris expert, Claire Austin, today, they are found in the wild in tones of blue, lavender, yellow, white, pink, and orange/red, the latter color not found in any other irises. Their flowers are large and flatter than other irises, with less of a distinction between the upward center petals and outer falls, the petals that droop on most irises. This unique flower form makes the Louisiana Iris, in some ways, especially when viewed from above, the most beautiful of all the worlds irises.
They need plenty of water, but a well-watered perennial border is fine. A wet spot in your garden or meadow is even better.
