Taxonomy
[edit | edit source]Although some floras recognize the North American populations of S. valerandi as a separate species (S. parviflorus) or subspecies (S. valerandi ssp. parviflorus),[8][9] a 2012 investigation based on molecular and morphological data indicated that S. vagans and S. parviflorus should not be regarded as separate species but as part of a widespread "S. valerandi species complex".[10]
Distribution
[edit | edit source]Samolus valerandi is widely distributed across western and Mediterranean Europe, north Africa, Asia and Australia, Central and South America including Cuba, and Japan.[11]
Ecological aspects
[edit | edit source]This species is found in a variety of wet habitats, including stream banks, tidal marshes, and seeps.[5] It can be found in both degraded and intact natural communities.[12]
Cultivation
[edit | edit source]The plant can be grown in ponds, bog gardens, and damp areas in the garden. S. valerandi prefers light (sandy), medium (loamy), and heavy (clay) soils, preferably neutral or basic (alkaline) soils. It can tolerate both shade and a bright, sunny position. It requires moist or wet soil and can even grow in water. The plant can tolerate maritime exposure and is self-fertile. S. valerandi is sometimes grown in aquariums, although they seem to last only a limited time when grown fully submersed.[citation needed]
Uses
[edit | edit source]The plant's leaves, when cut and agitated in water, produce a lather, for which reason in Palestine it has been used by the local Arab population, in former times, to launder clothes and was called by them sabūn 'arab (= Arab soap).[13]
