Pink knotweed (Persicaria capitata) is native to the Himalayas and was brought to Japan during the Meiji period for ornamental purposes. It has since naturalized and can now be found all across the country. Its flowers, which bloom from April to October, start out pink and later turn white. In Japan, pink knotweed is called 'princess Chinese knotweed' because its flowers and leaves are similar to, but smaller than, those of the Chinese knotweed (Persicaria chinensis). Some Japanese terms have hime as a prefix and the prefix means small and cute.
