The color of ruri is purplish blue, and matsuri (matsurika) means a species of jasmine endemic to India.
So the Japanese name Rurimatsuri refers to blue jasmine, but jasmine is a generic name of the plants belonging to
Oleaceae Jasminum. (Currently, Matsurika is the Japanese name
for a species of jasmine, Jasminum sambac.)
This plant can grow 2 to 4 m in height. It is almost ever-flowering.
The flower is azure and funnel-shaped. It has glandular hairs on its sepals around the floral tube that secrete mucus.
This plant contains plumbagin (5-Hydroxy-2-methyl-1,4-naphthoquinone) as a chemical defence substance.
It is a yellow needle crystal, is rather highly toxic (LD50 (rat, oral) 65 mg/kg) and also shows corrosivity.
