Type from Europe.
Epilobium parviflorum is one of the species of Epilobium in the flora region with a very wide distribution in western Eurasia (cf. Raven, 1962). As is true of many of the most common species, it grows often in disturbed places and in a wide range of habitats. It is one of the few species in the genus found in Baluchistan, south of the main Himalayan axis. Fl. Per.: Jul-Sep (-Nov). Fr. Per.: Aug-Oct (-Nov); Distribution: Europe to western China and North Africa; not common in the Himalayan region, especially in the east; adventive in North America and New Zealand.
