Prunus nipponica, also called Japanese alpine cherry (高嶺桜, Takanezakura), is a shrub which originates from the islands of Hokkaido and Honshu, Japan.[2] It grows to a height of about 5 meters (16 ft) and can grow in sandy, loamy, and clay soils.[3]
This species is one of the hardiest of cherry trees, well-suited to cold climates. The flowers are a very light pink or even white in color.[4] Flowers bloom in the first half of spring. They have 5 petals and are 3 centimeters (1.2 in) in diameter. The pistils are usually longer than the stamen. The leaves are serrated and the bark is gray.[5] In autumn the leaves turn yellow and orange-red; these are rare autumnal colors for a cherry tree.[6][7][8]
This species was first reported by Japanese botanist Jinzō Matsumura in the Tokyo Botanical Magazine in 1901.[10] It is in the section Pseudocerasus of the cherry subgenus Cerasus of the genus Prunus, which are ornamental plants. Ma et al classified it in a group with Prunus incisa.[11]P. nipponica is on the "List of Protected Animals and Plants in the Wildlife Protection Zone" of the wilderness Shirakami-SanchiWorld Heritage Site.[12]
