Creeping Smartweed (scientific name:Persicaria longiseta) is an annual grass of the genusfamily Polygonaceae. It is also called 'Aka Mamma(Japanese meaning is red rice)' because flowers and buds look purple pink and like red rice. The one that looks like a flower is a calyx, and in fact there is no flower (wreath)
Inotades are classified as single flowered flowers (monochlamydeous flower). In single flower-bloomed flowers, there are other items such as Shu-Meigiku (Autumn) and Chestnut.
