Continuing my series about Britain’s native trees…

In the early autumn sunshine, rowan trees can’t help but draw the eye.    Clusters of berries flash brilliant red against the feathery green foliage, swaying heavily in the wind, enticing hungry birds of all shapes and sizes to plunder them.

Rowan, Castle Lachlan JW 119The mountain ash (Sorbus aucuparia) has many names:  ‘rowan’ is perhaps the most familiar to us, but it is also known as the ‘quickbeam’, ‘sorb apple’, ‘wicken’, or ‘witchwood’.   In Irish its name is ‘caorthann‘, and in Gaelic ‘caorunn‘ (pronounced ‘coroon’).   A deciduous tree, it has lovely slender branches covered in silvery-grey bark, and distinctive leaves of between nine and 15 ‘leaflets’ arranged in opposing pairs.   The leaves have serrated edges, distinguishing them from those of ash trees, which are smooth.

Mountain ash flowersBetween May and June, a froth of creamy blossoms appear, sweet-scented to attract pollinating insects such as bees and beetles.   Later, these flowers are replaced by scarlet berries, irresistible to birds such as siskins, blackbirds and chaffinches;   even the portly black grouse are tempted up into the branches in search of food.   In the late summer and autumn, it’s exciting to watch flocks of fieldfares and redwings descending noisily on a mountain ash tree, before moving on swiftly after they’ve eaten their fill.

Preferring light acid soils, rowan trees are often seen braving the wind on a bare hillside, their roots having penetrated a crevice in a rock face.  They can also spring up in the shade of a Scots pine, their seeds having been dispersed by the droppings of birds sitting in the branches above.   An important species of the Caledonian Forest, the mountain ash doesn’t create its own woodlands but prefers to blend into forests of oak, birch and pine.

Rowan trees support an incredible amount of wildlife.  Quite apart from the birds and insects that feed on it, the branches are home to a wealth of fungi and lichen;  in fact, a newly-identified lichen that is endemic to Scotland grows mainly on rowan.   Red deer love browsing on its bark and leaves, and mountain hares will also nibble the young saplings.

Mountain ash (1)As you’d expect, the wood of the mountain ash is tough and strong, and traditionally it has been used to make tools, bows, walking sticks, spinning wheels, cart wheels and beams.   Druids carried staffs of rowan, and it has also been used as a dowsing rod.  The berries and the bark provided a dye for wool, while for centuries cooks have used rowan berries in a variety of sweet and savoury recipes, among them delicious jellies to be eaten as a relish with meat.

The rowan offered considerable health benefits, too:  a distillation of its bark was prescribed to cleanse the blood and alleviate stomach upsets.  The berries were eaten by sufferers of scurvy, as they contain high levels of Vitamin C.

The mountain ash in folklore

No tree has more mystical associations than the rowan.   Beloved by the druids, it is often found growing close to stone circles and ancient burial sites, where it is believed to protect the spirits of the dead.  Because of its white flowers it was considered a ‘faerie tree’, enhancing psychic powers and the appearance of visions.

In times gone by, sprigs of rowan were either worn or carried as a protection against evil;  these amulets would also be placed in a cattle shed to protect the cows (and their milk) from enchantment.  If a rowan tree took root next to a dwelling, it was considered great good fortune for all who lived there.  In old Irish legends, symbolic events often take place under a Quickening Tree, or mountain ash.

Mountain ash flowers (2)Housed in the Pitt Rivers Museum in Oxford are several loops and crosses of rowan, donated by the archaeologist Rev Canon John Christopher Atkinson in the late 19th century, and believed to have been made by an old man in Strathdon, Aberdeenshire.  To ward off evil, these crosses were traditionally placed above all the openings of a house on Lammas Day (1st August), by a person who was forbidden from speaking to anyone whom he chanced to meet;   there is another tale, which tells that they were placed there by a horseman who turned his horse three times before placing each loop.

According to a historian at The Pitt Rivers Museum, “...the people of Strathspey in Scotland would make a hoop of rowan tree on May-day and force sheep and lambs to pass through it, both in the morning and in the evening, so as to protect them against witchcraft.”

The Norse people held the rowan in similar esteem.  Their god, Thor, had been saved from a fast-flowing river when he clung to the branches of a mountain ash.   They believed that this was the tree from which woman was first made (the first man having been fashioned from an ash tree).   Its wood was preferred for the carving of ancient runic symbols, and in fact the word ‘rune’ is believed to share the same root as ‘rowan’.

Ancient mountain ash

Looking even further back in time, a Greek myth attempts to explain the berries’ bright colour.   Hebe, the goddess of youth, was the keeper of a magic chalice containing ambrosia, the nectar of the gods.  The chalice was stolen by demons, and the gods sent an eagle to retrieve it.  (I am sure this looked good, but I have to say they really should have got it themselves:  they were gods, after all.)  As it battled with the demons, the eagle was wounded and a few drops of blood spilled from its wounds;   these fell to the Earth and sprang up as rowan trees.  The leaves of the trees were said to represent the eagle’s feathers.

I don’t know about you, but next time I see a mountain ash I might stop for a few minutes to try and absorb some of its ancient magic!
