Veronica longifolia - Garden speedwell

Garden speedwell (Veronica longifolia) is a multi -year herbaceous plant from the family of Plantaginaceae. This species is widespread in Europe, Asia and Siberia and grows preferably in damp habitats such as river banks, floodplain forests and damp meadows. Due to its striking inflorescences, it is also a popular ornamental plant in natural gardens.
