Sorairoasagao includes several cultivarieties (cv.) that differ in flower color and pattern. Among them, Heavenly Blue has the most beautiful flower color and is sold at market under the name West morning glory. As the seed set is not so good, a lot of flowers open every morning even in Autumn. Photo of farm-cultivated plants, 1997.9.17 (slide 44). The blue of this flower is the blue of heaven (slide 45). The molecular structure of this pigment has been identified and named Heavenly Blue Anthocyan (HBA).
