The trees at Keele

We have over 150 species of tree on campus, not counting the 240 species and varieties of Flowering Cherry! Amongst them are many of our common native species as well as some more unusual ones. So, if you can't tell a Beech from a Birch or just want to know a bit more about them then read on!

Narrow-leaved Ash - Fraxinus angustifolia

Narrow-leaved Ash Origin: This tree is a native of southern Europe and was introduced to Britain around 1800. It is found infrequently in parks and gardens, mainly in the south.

It resembles the Common Ash but the winter buds are coffee-coloured (black in Common Ash), the leaves are 15 to 25 cm long with 7 to 13 narrow leaflets (broader in Common Ash) with jagged marginal teeth, 7 - 20mm long, narrowly tapering to the base; apex long-pointed.

The terminal leaflet is the only one with a stalk.The number of teeth usually equal the number of leaf veins whereas in Common Ash there are more teeth than veins.

In autumn, the leaves turn a beautiful rose-pink colour especialy in the form Claret Ash  'Raywood'.

The other ash at Keele with such narrow leaflets is the Caucasian Ash but that species has fewer leaflets and on the underside of the leaf at the base of each leaflet are brownish hairs. Narrow-leaved Ash is hairless (glabrous) beneath.

Location : with a collection of ashes; compartment 7a; square S17. One, form Claret Ash 'Raywood', between the Chapel and Tawney Building.
