Bidens also known as Winter Cosmos are combined with murasaki shikibu (common name: the Beauty Berry) widely distributed in the U.S.
The yellow bidens are in the aster family, but are closely related to the American genus Coreopsis. The plants are zoochorous; their seeds will stick to clothing, fur or feathers, and be carried to new habitat. This has enabled them to colonize a wide range, including many oceanic islands.
The purple berries dubbed Beauty Berries, are also known as Callicarpa, a genus of shrubs and small trees in the family Verbenaceae. A majority of the up to 150 species are native to Japan, East and southeast Asia, but may also be found in Australia, southeast North America and Central America.
Callicarpa japonica, native to Japan, often found wild in the wooded countryside is also cultivated in gardens. It is called Murasakishikibu in Japanese, in honor of Murasaki Shikibu.
