| Most species are native to temperate and tropical regions of the Northern Hemisphere. The best known trees of this family are olive and ash, while the most familiar shrubs are privet, lilac, and golden bell (Forsythia), all popular ornamental plants. Many members of the family are economically significant. The olive (Olea europaea) is important for its fruit and for the olive oil extracted from it. The ashes (Fraxinus) are valued for tough wood. Forsythias, lilacs, jasmines, osmanthuses, privets, and fringe trees are valued as ornamental plants in gardens and landscaping. At least two species of jasmine are the source of an essential oil. —Wikipedia |
