Common Rowan Sorbus aucuparia

The Common Rowan is native to Europe, Turkey and north Africa. In Britain it grows naturally on hillsides up to 1000m. It is also known as the Mountain Ash, because its leaves are similar to the Common Ash, although it is not related. It can now be found in many streets, parks and gardens where it is planted for its early flowers and colourful berries. The tree bears white flowers in April and red berries in July. The berries are eaten by birds.

Each leaf has up to 15 tooth-edged leaflets. The leaf shown here has 13 leaflets and is known as a pinnate leaf.

The berries are red by July. This type of fruit is called a ‘pome’ by botanists. It is very similar to that of the Whitebeam.

The tree is full of flower clusters like this in May. This type of flower cluster is called a ‘corymb’ by botanists.

The bark has horizontal lines of ‘lenticels’ which are breathing pores.
