Iris sanguinea is an herb perennial in Iridaceae, with both ornamental and medicinal value (Qi and Yang, 1988). It is mainly distributed in Heilongjiang, southern Jiangsu, Jilin, Liaoning, and Inner Mongolia, China; and surrounding countries, including Japan, Korea, Mongolia, and Russia (Zhao et al., 2000). It has specific characteristics including fast growth, extensive management, and simple cultivation and maintenance, and therefore, has a broad prospect of application in landscaping (Dong et al., 2014; Shang and Wang, 2014). Wild resources of I. sanguinea are abundant, but the color is mainly blue violet (Wang et al., 2016). Therefore, the improvement of flower color has become one of the interests in breeding of I. sanguinea. In 2013, a new light violet [Royal Horticultural Society (RHS) 85A] I. sanguinea cultivar Dream of the Butterfly was selected from a cross of I. sanguinea f. albiflora (RHS NN155C) × I. sanguinea (RHS N88A). After 4 years of observation and propagation, this cultivar had stable flower color and other major horticultural traits. Compared with its progenitors I. sanguinea and I. sanguinea f. albiflora, ‘Dream of the Butterfly’ has wider inner and outer perianths and shorter plant height with slenderer leaves.
