ML 39″
From Schreiner’s Catalog 1988, the Intro Year Catalog:
“This bombastic colossus is the largest Iris we know!. Held on ramrod stiff stems, the gargantuan 7 1/2″ x 5″ flowers literally flaunt their colors. This flamboyant variegata has arched golden ochre standards and solid rich mahogany red falls. 9 to 0 buds are displayed on extra sturdy three branched stems. Boldness in size, color and habit distinguish Supreme Sultan.”
