Manna Ash

Fraxinus ornus
Oleaceae (Olive family)
We grow the Manna Ash, Fraxinus ornus, as a lone specimen for maximum visual impact, close to the Grass Maze. It makes an attractive, domed tree that in early May is smothered in hay-scented, creamy-white flowers. The flowers have delicate, skinny petals gathered together into loose panicles, so that the whole tree looks to have been dusted in icing sugar!
The Manna Ash is native to southern Europe and southwestern Asia and belongs to the group of Tertiary trees, along with the Hop Hornbeam, Ostrya, and Caucasian Elm, Zelkova, grouped together on the South Walk, which never repopulated Britain after the last ice age.
