• Ash trees for the city


Which ash trees are suitable for the urban climate?

The flowering ash, also know as manna ash or Fraxinus ornus, is particularly well suited as a street tree because it tolerates road salt and is only affected by external influences when situated in paved locations. The dryness that often occurs in city locations is also hardly an issue for the tree. And its origin? Central and eastern North America!
The botanical name of the red ash alone, Fraxinus pennsylvanica, implies its area of origin, because as with Fraxinus ornus, it comes originally from the middle and east of North America. It is therefore also not a native grove, and when we look at its qualities, it becomes clear why we prefer Fraxinus pennsylvanica as a city tree: it not only tolerates road salt and dry soil, but can also handle wet soil. It is therefore well suited as a tree for streets and boulevards.
Likewise with Fraxinus americana (white ash), the botanical name also reveals its origin; we don’t need to make a guessing game out of it. The white ash has its origins in eastern North America and tolerates road salt just as well as partial paving. It is therefore ideal as a park and boulevard tree and also as a solitary tree in cities. Harmless and resistant These three ash trees alone show that the development of our urban climate is compelling us to look for groves in other countries and climate zones as well as on other continents.
And don’t worry: the types of ash trees listed here and the corresponding varities are all resistant to ash dieback.

This year, we will be taking some city trees to our stand at the GaLaBau in Nuremberg, from 12–15 September. You will find us and the trees in Hall 4 at Stand 109.
Be sure to stop by; we are always happy to have an exciting conversation about this and other topics.
