Manna Ash | Manna or Flowering ash (Fraxinus ornus) grows to a height of 8-20 metres (26.2-65.6 feet) in the wild in central and southern Europe, and occurs mainly in woodland and thickets. It has a rounded crown. It is easily recognised by its conical heads of white flowers, appearing when the leaves are still small. A sweet gum called ‘manna’ is exuded from the branches and is used in folk medicine.
