Abstract
A new and distinct hybrid variety Hibiscus moscheutos cultivar, particularly distinguished by having flowers of from ten to twelve inches in diameter that are pale pink (Red-Purple Group 69D) with deeper pink (Red-Purple Group 74C) on edges of petal margins and mottled over the petal intensifying slightly toward the center, with deeper red eye (Red-Purple Group 60A). The length of the blooming cycle is about four to five weeks. The flowers, which have completely overlapping petals, retain their flat shape for two full days, except when temperatures are exceptionally warm. Distinguishing characteristics are constant and stable in asexually reproduced plants.
