Шаблон:Short description Шаблон:Speciesbox
Dicentra peregrina (Japanese コマクサ komakusa) is a herbaceous perennial growing from a rhizome, native to mountains in Japan and nearby areas of East Asia.
Etymology
The species name peregrina is Latin for "exotic, alien, foreign, strange, from foreign lands", possibly because the species is the only one of its genus outside of North America.[1]
In Japanese, the plant (kusa)[2] is named for the buds, which look like the head of a horse (koma).[3]
Description
Leaves are gray-green, glaucous, and deeply cut, with linear lobes.
Flowers have four rose-purple, pink, cream, pale yellow, or white petals and two tiny sepals. Outer petals are pouched at the base and strongly bent back at the ends. Inner petals are long and protruding, connected at the end.
