Iris louisiana Sinfonietta Tony's Favorites surviving both 15 degrees FThe award winning Iris x louisiana 'Sinfonietta' forms a wide spreading (7' in 5 years) patch of 4' tall, dark green foliage, topped in early May (NC) with 6" wide, stunning navy blue flowers, each highlighted with yellow throats (nothing a little Zicam won't cure). As with all Louisiana iris, Iris 'Sinfonietta' loves swampy conditions, but we have grown this for years in typical garden soil with no ill effects.
