Russ O'Harra Hosta Society
The Russ O’Harra Hosta Society is an educational society, based in central Iowa, open to all those interested in the genus Hosta. Its purpose is to promote the growing and enjoyment of hostas, including their use in landscape design and the cultivation and development of new cultivars. The goals of the Society are in keeping with those of the American Hosta Society. Our society is named for Russ O'Harra, who was one of the most prominent hosta enthusiasts and hybridizers in the Midwest.

Mardi Gras by O. Petryszyn (r2001)
The Mardi Gras celebration in New Orleans has just ended, a bit early this year. It is an almost bizarre mixture of religion, music, dancing, parades, beads, and booze, but memorable in any case! Even if you don't go to New Orleans, H. 'Mardi Gras' may remind you to have fun in your garden.
H. 'Mardi Gras' has medium to dark green leaves with wide, creamy white margins that are slightly rippled and have jagged indentations. The leaves are very shiny on top and dull underneath. Pure white flowers are produced in early to mid summer. It is a hybrid of 'Christmas Tree Gala' and H. nigrescens 'Elatior'. H 28" W 38"
