- In the 18th of the Nature Conservation Series of postage stamps, the Japanese Ministry of Posts and Telecommunication will be issued a 50-yen stamp showing “sakuraso” (Primula sieboldi f. spontanea).
- “Sakuraso” (primrose) is a perennial plant belonging to Primula of dicotyledon. It grows in wetland in mountains and near rivers throughout Japan. It also can be seen in the Korean peninsula and the eastern part of Siberia.
- The egg-shaped leaf is about 10 centimeters long and has wrinkles on its surface. The 15-40 centimeters long caulis which grows between leaves has several crimson flowers at its tip. Each flower has five petals with a diameter of two or three centimeters. They look like cherry flowers. The “Sakura-so” flowers bloom between the middle of April and early May.
- Tajimagahara in Urawa City, Saitama Prefecture, is known for the growing of the herb. It was designated by the Government as a special monument in July in 1920. But with the progress of urbanization in the area, the number of Sakuraso growing in the area began to decrease in latter years. In order to give stronger protective measures, the Government designated the area as a Special Natural Monument on March 29, 1952.
