What is Spatterdock
Spatterdock or Kohone (scientific name: Nuphar japonicum) is native to Japan, the Korean Peninsula, Taiwan, and is a perennial aquatic plant of the family Nymphaeaceae water lily. A golden flower makes bloom at the tip of an elongated flower stalk in a pond or shallow water. The flowers consist of calyx which seems like a petal of large petals (stamen) -> large number of petals (stamen) -> long and thin petals -> petals from the center towards the periphery. Leaves are bigger than flowers. Nauhalidine, an alkaloid contained in the rhizomes, is regarded as a tonic, hemostatic agent, and becomes a herbal medicine named Senkotsu. Flower language is "secret affection". In the same genus, there is Himekohon (scientific name: Nuphar subintegerrimum) that makes smaller flowerss bloom than Kohone (Nuphar japonicum) .
Differences between Himé-Kôhone and Kôhone
Both Himé-Kôhone (Nuphar subintegerrimum) and Kôhone (Nuphar japonicum) have similar heights, ranging from 10 to 40 cm. Himé-Kôhone, also known as "Dwarf Cow-lily," produces flowers that look like a smaller version of Kôhone's flowers, with a less deeply notched stigma disk in the center. The most noticeable difference is in the shape and position of their leaves. Himé-Kôhone has round, floating leaves, while Kôhone has long, elliptical aerial leaves.
"Floating leaves" are leaves that remain on the surface of the water, with roots anchored in the soil at the bottom.
"Aerial leaves" are leaves that rise above the water surface and open in the air.
