Scotch Broom; Cytisus scoparius (L.) Link

Pea Family; LEGUMINOSÆ (FABACEÆ) 

The broom is native to Great Britain and grows in abundance along the heaths, moors, and in open spaces.  It is a smallish tree, rarely growing above 7 feet tall, and is rather thick and bushy.  Its stems are long, thin, and green.  From them sprout an abundance of pod-shaped yellow flowers, which bloom in the summer.  The broom is closely related to the gorse bush.   

The reed or the broom is the tree sacred to the twelfth moon of the year starting on October 28th and ending on November 24th. The ogham is nGetal.  This tree is useful in "cleaning up" spiritual or mental messes.  It is used to correct or heal damage or injury.  For instance, if you are having malevolent thoughts, emotions, or actions, use the broom to help you get rid of them.  Think of this tree as the herald of new beginnings.   

On the mundane level the broom has many uses.  One obvious use is using the stems to fashion a besom.  A decoction of broom is useful for gout, sciatica, painful joints, malaria, and fever.  Take care because too large a dose can cause extreme bouts of vomiting.  

Scotch Broom is a very common big bushy weed. Some people will object to calling it a weed. Some people think the moon is made of cheese. Scotch Broom is weedy even though ordinary vegetable-gardeners may not think so. 

From Western Europe originally, it is the best known of various kinds of Brooms, named because useful sweeping brooms are easily made from the twiggy brush. Why it is called Scotch or Scot's Broom is a mystery, though it is also called Common Broom or Broom, period. The scientific name Cytisus is adapted from an ancient Greek name; the Latin specific name scoparius means broom-like.

Introduced to the Pacific Northwest by Captain Colquhoun Grant of Sooke, Vancouver Island, around 1850, Scotch Broom quickly invaded coastlines, meadows, roadsides, clearcuts and other open sunny areas. Because of its wanton reproduction, forming sometimes choking colonies, it has long been considered too much of a good thing. 

It has wiry, grooved evergreen twigs, but also tiny clover-like leaves in summer, especially prominent on the young plants only a foot or two tall. The slender twiggy branches are tough to break, flexible and strike me as quite the thing for broom-making. Probably they should be gathered for this purpose during fall or winter. 

Though sporadic flowers can be seen every month (even December and January) the main explosion of yellow is from late April into May and June, when it erupts into scented bright yellow or red-spotted blossoms, of piercing drama. Everybody knows it then. Allergy-sufferers curse its pollen. Bees joyfully court it. In August the flat seedpods, an inch or two long, hairy on the edge, and very dark, have dried enough to explode with popping noises, thereby making meadows lively with sound. 

The flowers are so unstinting and pretty that garden versions and hybrids such as 'Moonlight' are planted in masses along freeways and in other barren, ugly sites. For most Brooms tolerate with easy nonchalance baking sunny sites and poor soil. Severe wintry blasts alone sometimes kill them back. But nobody pities the Broom. We know darn well how it returns with strength unabated in spring. Cast-iron weeds they are, or admirable, tough garden plants, according to how many we have. 

A great plus is Broom's ability to fix nitrogen through root-nodule symbiosis. Meaning, unlike most plants, which grow poorly in soils low in nitrogen, Broom thrives by simply making its own nitrogen even as porcupines make their own armor of needles. Uproot a Broom and you can see plainly little roundish swellings: these do the trick. Most members of the pea family (leguminosæ), besides a few other plants such as alders, can do this. The result is a richer soil every year. 

It is a short-lived plant, quickly reaching about 6 to 12 feet tall, then dying and presenting a scrawny, scratchy mass of tinder: dangerous fuel for brush fires. Though the fresh green plant is easily sliced or cut, the dry dead wood is hard, brittle and incendiary. A spiny broom called Gorse, Furze or Whin is Ulex europæus, neither as common or well known, but also a weedy yellow-blossomed introduced shrub. Dyer's Broom, Genista tinctoria, is still another yellow-flowered wild bushy weed, of even less consequence. 

In bygone times the flowerbuds were pickled as caper substitutes by some folks. A tea of the plant was used to combat gallstones, and other therapeutic uses prescribed. Some people brewed a coffee from the roasted seeds. California Quail are said to eat the seeds. However, since the plant contains toxic alkaloids it should be considered poisonous.

In the Language of Flowers, Broom signifies variously: mirth, neatness or humility. The neatness is obvious for a broom-plant. The mirth is a joke beyond my understanding; the humility may initially seem at odds with such a conquering globetrotter, but must have reference to its being used to sweep dust. So Scotch Broom cannot be condemned as altogether vile: it improves soil, is a good erosion-control plant, is pretty, is tough, supplies broom-material, and pleases bees. Florists can use it somewhat, too. On the other hand, it is a too-abundant plant, fire hazard, and toxic to livestock.

From A Modern Herbal by Mrs. M. Grieve

Its long, slender, erect and tough branches grow in large, close fascicles, thus rendering it available for broom-making, hence its English name. Broom was used in ancient Anglo-Saxon medicine and by the Welsh physicians of the early Middle Ages. It had a place in the London Pharmacopceia of 1618 and is included in the British Pharmacopoeia of the present day.

Bartholomew says of Broom:  

'Genesta hath that name of bytterness for it is full of bytter to mannes taste. And is a shrub that growyth in a place that is forsaken, stony and untylthed. Presence thereof is witnesse that the ground is bareyne and drye that it groweth in. And hath many braunches knotty and hard. Grene in winter and yelowe floures in somer thyche (the which) wrapped with hevy (heavy) smell and bitter sauer (savour). And ben, netheles, moost of vertue.'  

Description---It grows to a height of 3 to 5 feet and produces numerous long, straight, slender bright green branches, tough and very flexible, smooth and prominently angled. The leaves are alternate, hairy when young the lower ones shortly stalked, with three small, oblong leaflets, the upper ones, near the tips of the branches, sessile and small, often reduced to a single leaflet. Professor G. Henslow (Floral Rambles in Highways and Byways) says with reference to the 'leaves' of the broom: 'It has generally no leaves, the green stems undertaking their duties instead. If it grows in wet places, it can develop threefoliate leaves.' The large bright yellow, papilionaceous, fragrant flowers, in bloom from April to July, are borne on axillary footstalks, either solitary or in pairs, and are succeeded by oblong, flattened pods, about 1 1/2 inch long, hairy on the edges, but smooth on the sides. They are nearly black when mature. They burst with a sharp report when the seeds are ripe flinging them to a distance by the spring-iike twisting of the valves or sides of the pods. The continuous crackling of the bursting seed-vessels on a hot, sunny July day is readily noticeable. The flowers have a great attraction for bees, they contain no honey, but abundance of pollen.

'In flowers without honey, such as the Broom, there is a curious way of "exploding" to expel the pollen. In the Broom the stigma lies in the midst of the five anthers of the longer stamens, and when a bee visits the flower those of the shorter explode and disperse their pollen on the bee pressing upon the closed edges of the keel petal. "The shock is not enough to drive the bee away . . . The split now quickly extends further . . . when a second and more violent explosion occurs." The style was horizontal with a flattened end below the stigma; but when freed from restraint it curls inwards, forming more than a complete spiral turn. It springs up and strikes the back of the bee with its stigma. The bee then gathers pollen with its mouth and legs.' (From The Fertilization of Flowers, by Professor H. Mueller, pp. 195-6)

History---As a heraldic device, the Broom was adopted at a very early period as the badge of Brittany. Geoffrey of Anjou thrust it into his helmet at the moment of going into battle, that his troops might see and follow him. As he plucked it from a steep bank which its roots had knit together he is reputed to have said: 'This golden plant, rooted firmly amid rock, yet upholding what is ready to fall, shall be my cognizance. I will maintain it on the field, in the tourney and in the court of justice.' Fulke of Anjou bore it as his personal cognizance, and Henry II of England, his grandson, as a claimant of that province, also adopted it, its mediaeval name Planta genista, giving the family name of Plantagenets to his line. It may be seen on the Great Seal of Richard I, this being its first official, heraldic appearance in England. Another origin is claimed for the heraldic use of the Broom in Brittany. A prince of Anjou assassinated his brother there and seized his kingdom, but being overcome by remorse, he made a pilgrimage to the Holy Land, in expiation of his crime. Every night on the journey, he scourged himself with a brush of 'genets,' or genista, and adopted this plant as his badge, in perpetual memory of his repentance. St. Louis of France continued the use of this token, founding a special order on the occasion of his marriage in the year 1234. The Colle de Genet, the collar of the order, was composed alternately of the fleur-de-lys of France and the Broomflower, the Broomflower being worn on the coat of his bodyguard of a hundred nobles, with the motto, 'Exaltat humiles,' 'He exalteth the lowly.' The order was held in great esteem and its bestowal regarded as a high honour. Our Richard II received it, and a Broom plant, with open, empty pods, can be seen ornamenting his tomb in Westminster Abbey. In 1368 Charles V of France bestowed the insignia of the Broom pod on his favourite chamberlain, and in 1389 Charles VI gave the same decoration to his kinsmen.

The Broom is the badge of the Forbes. Thus, according to Sandford, it was the bonny broom which the Scottish clan of Forbes wore in their bonnets when they wished to arouse the heroism of their chieftains, and which in their Gaelic dialect they called bealadh, in token of its beauty.

'This humble shrub,' writes Baines, 'was not less distinguished than the Rose herself during the civil wars of the fourteenth century.'

Apart from its use in heraldry, the Broom has been associated with several popular traditions. In some parts, it used to be considered a sign of plenty, when it bore many flowers. The flowering tops were used for house decoration at the Whitsuntide festival but it was considered unlucky to employ them for menial purposes when in full bloom.

An old Suffolk tradition runs:

'If you sweep the house with blossomed Broom in May

You are sure to sweep the head of the house away.'  

And a yet older tradition is extant that when Joseph and Mary were fleeing into Egypt, the plants of the Broom were cursed by the Virgin because the crackling of their ripe pods as they touched them in passing risked drawing the attention of the soldiers of Herod to the fugitives.

The Broom has been put to many uses. When planted on the sides of steep banks, its roots serve to hold the earth together. On some parts of our coast, it is one of the first plants that grow on the sand-dunes after they have been somewhat consolidated on the surface by the interlacing stems of the mat grasses and other sand-binding plants. It will flourish within reach of sea spray, and, like gorse, is a good sheltering plant for sea-side growth.

Broom is grown extensively as a shelter for game, and also in fresh plantations among more important species of shrubs, to protect them from the wind till fully established.

The shrub seldom grows large enough to furnish useful wood, but when its stem acquires sufficient size, it is beautifully veined, and being very hard, furnishes the cabinetmaker with most valuable material for veneering.

The twigs and branches are serviceable not only for making brooms, but are also used for basket-work, especially in the island of Madeira. They are sometimes used in the north of England and Scotland for thatching cottages and cornricks, and as substitutes for reeds in making fences or screens.

The bark of the Common Broom yields an excellent fibre, finer but not so strong as that of the Spanish Broom, which has been employed from very ancient times- it is easily separated by macerating the twigs in water like flax. From the large quantity of fibrous matter contained, the shoots have been used in the manufacture of paper and cloth.

Tannin exists in considerable amount in the bark, which has been used in former times for tanning leather.

Before the introduction of Hops, the tender Freen tops were often used to communicate a bitter flavour to beer, and to render it more intoxicating.

Gerard says of the Broom:

'The common Broom groweth almost everywhere in dry pastures and low woods. It flowers at the end of April or May, and then the young buds of the flowers are to be gathered and laid in pickle or salt, which afterwards being washed or boiled are used for sallads as capers be and be eaten with no less delight.'  

Broom buds were evidently a favourite delicacy, for they appeared on three separate tables at the Coronation feast of James II. The flowers served the double purpose of an appetizer and a corrective.

Sometimes a bunch of green Broom tied up with coloured ribbons was carried by the guests at rustic weddings instead of rosemary, when that favourite aromatic herb proved scarce.

Withering (Arrangement of Plants) stated that the green tops were a good winter food for sheep, preventing rot and dropsy in them.

The blossoms were used for making an unguent to cure the gout, and Henry VIII used to drink a water made from the flowers against the surfeit.

Dodoens (Herbal, 1606) recommended a decoction of the tops in dropsy and for 'stoppages of the liver.'

Gerard tells us: 'The decoction of the twigs and tops of Broom doth cleanse and open the liver, milt and kidnies.'

Culpepper considered the decoction of Broom to be good not only for dropsy, but also for black jaundice, ague, gout, sciatica and various pains of the hips and joints.

Some of the old physicians burned the tops to ashes and infused the salts thus extracted in wine. They were known as Salts of Broom (Sal Genistae).

The powdered seeds are likewise administered and sometimes a tincture is employed. Bruised Broom seeds were formerly used infused in rectified spirit, allowed to stand two weeks and then strained. A tablespoonful in a glass of peppermint water was taken daily for liver complaints and ague.

The leaves or young tops yield a green dye.

The seeds have similar properties to the tops, and have also been employed medicinally, though they are not any longer used officially. They have served as a substitute for coffee.
