Everything about Rowan totally explained
The
rowans are
plants in the family
Rosaceae, in the
genus Sorbus, subgenus
Sorbus. They are native throughout the cool temperate regions of the
Northern Hemisphere, with the highest species diversity in the mountains of western
China and the
Himalaya, where numerous
apomictic microspecies occur. The name
rowan was originally applied to the species
Sorbus aucuparia.
Botany
Rowans are mostly small
deciduous trees 10-20 m tall, though a few are
shrubs. The
leaves are arranged alternately, and are
pinnate, with (7-)11-35 leaflets; a terminal leaflet is always present. The
flowers are borne in dense
corymbs; each flower is creamy white, and 5-10 mm across with five petals. The
fruit is a small
pome 4-8 mm diameter, bright orange or red in most species, but pink, yellow or white in some Asian species. The fruit are soft and juicy, which makes them a very good food for
birds, particularly
waxwings and
thrushes, which then distribute the rowan
seeds in their droppings.
Rowan berries as food
The berries of
European Rowan (
Sorbus aucuparia) can be made into a slightly bitter
jelly which in
Britain is traditionally eaten as an accompaniment to
game, and into
jams and other preserves, on their own, or with other fruits. The berries can also be a substitute for
coffee beans, and have many uses in
alcoholic beverages: to flavour
liqueurs and
cordials, to produce
country wine, and to flavour
ale.
Rowan
cultivars with superior fruit for human food use are available but not common; mostly the fruits are gathered from wild trees growing on public lands.
Rowan berries contain
sorbic acid, an acid that takes its name from the Latin name of the genus
Sorbus. Raw berries also contain
parasorbic acid (about 0.4%-0.7% in the European rowan), which causes
indigestion and can lead to
kidney damage, but
heat treatment (
cooking, heat-
drying etc.) and, to a lesser extent, freezing, neutralises it, by changing it to the benign sorbic acid. Luckily, they're also usually too astringent to be palatable when raw. Collecting them after first frost (or putting in the freezer) cuts down on the bitter taste as well.
Folk-medicinal uses
Fresh rowan berry juice is usable as a laxative, gargle for sore throats, inflamed tonsils, hoarseness, and as a source of
vitamins
A and
C. Rowan berry jam will remedy diarrhea. An infusion of the berries will benefit
hemorrhoids and
strangury. The bark can also be used as an astringent for loose bowels and vaginal irritations. Rowan is also used for eye irritations, spasmic pains in the uterus, heart/bladder problems, neuralgia, gout and waist constrictions.
Mythology and folklore
The European rowan (
S. aucuparia) has a long tradition in European mythology and folklore. It was thought to be a magical tree and protection against malevolent beings.
The density of the rowan wood makes it very usable for walking sticks and
magician's staves. This is why druid staffs, for example, have traditionally been made out of rowan wood, and its branches were often used in
dowsing rods and
magic wands. Rowan was carried on vessels to avoid storms, kept in houses to guard against lightning, and even planted on graves to keep the deceased from haunting. It was also used to protect one from
witches. Often birds' droppings contain rowan seeds, and if such droppings land in a fork or hole where old leaves have accumulated on a larger tree, such as an
oak or a
maple, they may result in a rowan growing as an
epiphyte on the larger tree. Such a rowan is called a "flying rowan" and was thought of as especially potent against witches and their
magic, and as a counter-charm against sorcery. Rowan's alleged protection against enchantment made it perfect to be used in making
rune staves (Murray, p. 26), for metal divining, and to protect cattle from harm by attaching sprigs to their sheds. Leaves and berries were added to
divination incense for better
scrying.
In Finland and Sweden, the number of berries on the trees was used as a predictor of the
snow cover during
winter. This is now considered mere superstition (however one can hear old men talk of it), as fruit production is related to weather conditions the previous
summer, with warm, dry summers increasing the amount of stored sugars available for flower and fruit production; it has no predictive relationship to the weather of the next winter. Contrary to the above, in Malaks, Swedish Finland the opposite was thought. If there rowan flowers were plentiful then the rye harvest would also be plentiful. Similarly, if the rowan flowered twice in a year there would be many potatoes and many weddings that autumn. And in Sibbo people are noted as having said that winter began first when the
waxwings (
Bombycilla garrulus) had eaten the last of the rowan berries.
In Sweden it was also thought that if the rowan trees grew pale and lost color, the fall and winter would bring much illness.
Etymology and other names
The name "rowan" is derived from the
Old Norse name for the tree,
raun or
rogn. Linguists believe that the Norse name is ultimately derived from a
proto-Germanic word *
raudnian meaning "getting red" and which referred to the red foliage and red berries in the autumn. Rowan is one of the most familiar wild trees in the
British Isles, and has acquired numerous English folk names. The following are recorded folk names for the rowan: Delight of the eye (Luisliu), Mountain ash, Quickbane, Quickbeam, Quicken (tree), Quickenbeam, Ran tree, Roan tree, Roden-quicken, Roden-quicken-royan, Round wood, Round tree, Royne tree, Rune tree, Sorb apple, Thor's helper, Whispering tree, Whitty, Wicken-tree, Wiggin, Wiggy, Wiky, Witch wood, Witchbane, Witchen, Witchen tree. Many of these can be easily linked to the mythology and folklore surrounding the tree. In
Gaelic, it's Rudha-an (
red one, pronounced quite similarly to English "rowan").
[
One particularly confusing name for rowans, used primarily in North America, is "mountain ash", which falsely implies that it's a species of ash (Fraxinus).][ The name arises from the superficial similarity in leaf shape of the two trees; in fact, the rowan doesn't belong to the ash family, but is closely related to the apples and hawthorns in the rose family.]
In the Canadian province of Newfoundland and Labrador this species is commonly referred to as a "Dogberry" tree.
