Komurasaki

This is 'ko-murasaki or murasaki-shikibu. '

This plant seems to have nothing to do with Murasaki Shikibu who wrote 'Genji-story'.
It was written about AD 1000, the Heian era in Japan and the oldest long novel in the world.
It is a treasure in Japan and in the world too.

This plant might be named like this because the color of the seeds are violet.
