Rosa hirtula

Rosa hirtula, the sanshou-bara or Hakone rose, is a species of flowering plant in the family Rosaceae.[1][2] It is found only in the vicinity of Mount Fuji and neighboring Mount Hakone in Japan, and is the town flower of Hakone.[3][4] The pale pink, single flowers can be as wide as 7.5 cm (3 in).[2] Quite unusually for a rose, it can take on a tree-like growth form.[5]
