Origin and general distribution
Ssp. sepium is assumed to be a native species of the archipelago and southern sea shores, growing in shrubs, grasslands and piled-up algae. However, this assumption has recently been called into question and the species was more probably introduced to Finland, possibly as early as the 1700s. The first written record of the species dates back to 1754 (Kalm). Turku Academy is believed to have spread the plant in the 1750s and 1760s. The first specimen of Ssp spectabilis was recorded in Finland in 1929, but it is likely to have been cultivated in this country considerably earlier.
Hedge bindweeds were common ornamentals in inland southern and central Finland, from where it often escaped to shrubs on riversides, and into wastelands and landfills.Ssp. spectabilis is an ornamental probably originating in Siberia. It has occasionally escaped from gardens into nearby shrubs and landfills.
