Habitat

Rowan (Sorbus aucuparia) in a woodland

A UK native, Rowan can be found in woodland, particularly along edges and rides, and growing at high altitudes. It is easy to grow, with attractive fruit, so is often found in gardens and parks.

Overall structure

The structure of rowan (Sorbus aucuparia)

Rowan is a slender tree reaching 15 m tall. Its canopy branches out from roughly 1/3 of the trees height.



Leaves

A leaf of rowan (Sorbus aucuparia)

The pinnately compound leaves consist of five to eight pairs of lance-shaped leaflets that have a serrated edge. The terminal leaflet is similarly-shaped to the leaflet pairs.


Trunk

The trunk of rowan (Sorbus aucuparia)

The back is a silver-brown to silver-grey and is quite shiny in younger specimens. It has horizontal markings.

Flowers

Flowers of rowan (Sorbus aucuparia)

The flowers form in springtime and are arranged on corymbs that appear to be densely packed. The individual flowers are creamy white, have five petals and the external reproductive parts are exposed. The flowers emit an unpleasant fishy aroma.

Fruit

Fruits of rowan (Sorbus aucuparia)

The spherical fruits turn deep orange-red when ripe and reach around 1cm in diameter. The combined weight of them is so heavy that branches can bend or even snap under their weight. The remains of the external reproductive parts are visible at the bottom of each fruit.

Possible lookalikes

An elder (Sambucus nigra)

Ash (Fraxinus excelsior) could be confused with rowan but its leaflets are not particularly serrated and it does not produce berries. Elder (Sambucus nigra) may also be confused with rowan but it usually has lots of canes rather than one solid trunk, it has less leaflets on its leaves (maximum three pairs) and its berries are purple-black rather than orange-red.

In addition, the seeds are believed to contain cyanogenic glycosides and hydrogen cyanide so should not be eaten


Other uses An anti-ageing skin mask has been made from the berries, while the branches produce a black dye. The wood is prized by woodturners.  Importance to other species Rowan's leaves are eaten by the larvae of many moths and butterflies, including the larger Welsh wave and autumn green carpet, while apple fruit moth caterpillars feed on the berries. The berries are also an important food source for birds, including blackbird, mistle thrush, redwing, redstart, fieldfare, waxwing and song thrush.

Always stay safe when foraging. You need to be 100% sure of your identification, 100% sure that your foraged item is edible, and 100% sure that you are not allergic to it (it is good practice to always try a small amount of any new food you are consuming). If in doubt, leave it out!
