1) KIKYŌ
Kikyō (桔梗) are increasingly rare in the wild. Popularly offered to the dead at Obon, the flower represents elegance, refinement, & honesty.
The roots are believed to help with coughs & phlegm.
Akechi Mitsuhide (明智光秀 1528-82) used the flower for his crest.
The Genji-no-tei (源氏庭) was designed in 1965, inspired by Heian period gardens. Kikyō offer the only colour.
White gravel is shaped into a pattern known as Genji Kumogata, imitating the gold clouds seen on The Tale of Genji scrolls.
