Know Your Ash Trees

Ashes can live up to 150 or 200 years.  Mature trees often have a ‘candelabra’ shape with branches sweeping down then up.

The best way to identify them is by the sooty buds.  They occur in pairs with each pair at right-angles to the next, with a triple at the end.

The seeds are also distinctive, if they are present on a tree.  These “bunches of keys” form soon after the flowers in spring; some will stay on for most of the year.

The leaves are light green and are divided into paired leaflets with a single one at the end.

The young stem is light in colour and smooth.  It gets more gnarled and pitted as the tree gets older.

Don’t confuse Ash with …
Rowan (“Mountain Ash”).  Rowan leaves are smaller and more serrated, and it has bright red berries not keys.  Rowan is a very different species and does not suffer from Ash Dieback.

Elder.  Elder leaves are a bit larger and rounder than those of Ash.  It is more bushy, where Ashes grow straighter.  Elder has berries not keys.
