|Crab-shaped peony||Konoe peony|
A deciduous shrub of the peony family, this plant was introduced from China, where people used the petals for food and the roots for medicine, in addition to appreciating the colorful blooms. The Japanese also admired the peony, which was first used in patterns for clothes and oxcarts, and later became a family crest. (From 'Family Crests of Japan' ICG Muse, Inc.2001)
