Persicaria orientalis
Also called Princess Feather, Oriental Smartweed, Prince's Plume, Prince's Feather, Prince's Plume Knotweed
Persicaria orientalis is a species of flowering plant in the family Polygonaceae, known as kiss-me-over-the-garden-gate and princess-feather. It was first described, as Polygonum orientale, by Carl Linnaeus in 1753. It was transferred to the genus Persicaria by Édouard Spach in 1841. Its native distribution is unclear. As of April 2023, Kew's Plants of The World Online lists its native distribution as ranging from the Russian far east to Indochina, Malesia and Australia. It is widely cultivated and naturalized.
