Fraxinus excelsior

Fraxinus excelsior - European (common) ash

 

European ash grows naturally in southern Finland, but is the most demanding of all the native broadleaf species with regard to where it grows. It develops best on rich, very moist slopes. The northernmost parts of its range are wet bogs where there is movement of ground water. When planted, the ash survives somewhat further north, especially on protected sites, but for park plantings even central Finland demands hardier ash species from North America or Asia.
