About
Fraxinus ornus, the manna ash or South European flowering ash, is a species of Fraxinus native to Southern Europe and Southwestern Asia, from Spain and Italy north to Austria and the Czech Republic, and east through the Balkans, Turkey, and western Syria to Lebanon and Armenia.
How to grow it
Fraxinus ornus is frequently grown as an ornamental tree in Europe north of its native range for its decorative flowers—the species is also sometimes called "flowering ash". Some cultivated specimens are grafted on rootstocks of Fraxinus excelsior, with an often very conspicuous change in the bark at the graft line to the fissured bark of the rootstock species.
A sugary extract from the sap may be obtained from the bark of the tree; which was compared to biblical manna in late medieval times (attested circa 1400 AD), giving rise to the name of the tree in English, Spanish (fresno del maná), and Italian (frassino da manna). Likewise, the sugar alcohol mannitol derives its name from the extract.
