Ash ( Fraxinus)
A tree or shrub, of the genus Fraxinus , belonging to the Oleaceae family. Found principally in northern temperate zones. Ash trees usually display small clusters of greenish flowers and wind-disperse their characteristic long-winged fruit. The white ash ( F. americana ) is used as a source of durable hardwood timber while the blue ash ( F. quadrangulata ) provides a blue dye, hence the name. The mountain ash and prickly ash are not members of this genus. [ 2 ]

the ash, lilac, true jasmine and Forsythia . The olive branch has
long been a symbol of peace. [ 4 ]
