General Description:

12"-30" (30-75cm) tall, with blue to red-violet flowers with white signals (D. Kramb, 08-NOV-03)

It flowers from May to July and is found all over Japan with the exception of Okinawa Island which is located in a sub-tropical zone. The flowers in dark reddish-purple and falls have white hafts with a network of blue-purple veins. Botanists sometimes find it difficult to distinguish between I.sanguinea and I.sibirica . As a feature of simple identification, it is said that the flower stalk of I.sanguinea is non-branching. However, I have found a wild branching form at Karei-highland in central Honshu. There are two variants of I.sanguinea in Japan: var.albiflora and var.violacea. (D. Kramb, 15-JAN-06)
