What is baika-mo

Baika-mo ( scientific name: Ranunculus nipponicus var. submersus) is a variety of the evergreen perennial submerged plant "Ginkgo baika-mo (Ranunculus nipponicus)," which is endemic to Japan. It is found in cold, clear streams such as rivers, canals, and springs. It has no floating leaves. It grows by creeping in the water, with adventitious roots emerging from the nodes and anchoring to the bottom of the water. The grass is 1 m to 2 m long, and the stems are soft and easily broken. It germinates and reproduces from the nodes of broken stems. It branches at the lower part of the stem. The leaves are dark green, 2 to 7 cm long, and are attached to the stem in alternate clusters. The flower stalks extend from the upper leaf axils underwater and produce numerous five-petaled white flowers resembling plum blossoms. The flowers bloom all year round, but are at their peak from June to September. A single nectary gland at the base of each petal attracts insects.
