05. Weeping Ash

Weeping Ash

Fraxinus excelsior L. ‘Pendula’


Sadly, this tree was felled in August 2022 due to infection by ash dieback. All the weeping ash in the Gardens were lost and several large mature trees were also felled. We have retained 5 large trees that are currently healthy and these trees are now monitored on a yearly basis at leaf burst.


We have retained part of the trunk on the ground within the Gardens to watch how the wood decays, the trunk will play a role in forming a vital habitat for invertebrates and the biodiversity that exists around decay and recycling.


The range of Fraxinus excelsior extends through Europe as far as the Caucasus.

  • ‘Pendula’ is a cultivar of a tree that is native to the British Isles. It became available from nurseries in the mid-18th century.
  • All the ‘Pendula’ cultivars are believed to descend from a single tree found in the parish of Gamlingay, Cambridgeshire.
  • The original tree was small so all the taller trees were grafted high up to produce a tall, clear trunk with upper pendulous branches.
  • This tree was a gift to the original Glasgow Botanic Gardens (at Sandyford, near Sauchiehall Street) from nurseryman, Robert Austin.  Having been planted in 1818 it was then moved to its current site in 1841.
  • Ash wood is very strong and flexible.  Tests show ash to have “greater toughness (impact strength) than any other home-grown hardwood.
  • The timber is a white wood that was used historically in the making of tool handles and coach building.
  • The foliage made good fodder for livestock.
  • Ash populations are now threatened by a fungal disease, ash dieback (Chalara fraxinea). This kills young trees very quickly but can take some time to destroy mature trees. In Europe, affected countries have lost 60-90% of their ash trees.
  • The tree does not have an IUCN rating.

Ash trees have very distinctive diagnostic features which help to identify the tree even when leafless. These include, hard black buds, grey smooth bark with some vertical, shallow fissures and twigs that become flattened around the buds.
