Iris sanguinea is a perennial flowering ornamental landscape plant (Shang and Wang, 2014; Wang et al., 2013). Natural hybridization occurs among cultivars, and the original wild species exists and makes abundant flower colors available in natural population. The flowers of I. sanguinea are mainly violet (RHS N88A), whereas I. sanguinea f. albiflora is white (RHS N155C). In recent years, some new flower colors and shapes of cultivars, such as ‘Zi Die’ (Dong et al., 2014), ‘Beautiful Lotus’ (Wang et al., 2016), ‘Bandie’ (Wang and Wang, 2017), and ‘Forest Fairy’ (Kuwantai et al., 2018), have been developed. In 2017, ‘Zi Meiren’ was released as a new cultivar from a naturally hybridized population of I. sanguinea. Its inner and outer perianths are purple (RHS 76C) with dark purple violet (RHS N82A) spots and stripes, and the color of the edge of the perianths turns to light (purple, RHS 76D). The inner perianth spreads outward, and the angle of the half of spoon part of the inner perianths droop down nearly 30°.
