Heraldry

The wild flag iris was a traditional natural dye used for both tartan and tweed. The roots were harvested and processed with bog iron or copperas as a mordant to make either black or dark blue dyes; they were also made into ink. The leaves were also made into dyes for tartans and tweed providing a bright green dye when mixed with alum as mordant.

The roots were also used medicinally in many parts of the Highlands. In his 'History of Scottish Medicine', (1932) John D Comrie speaks of their use as a laxative by Gaels in the Middle Ages. The author Martin Martin (c. 1660-1719) from Bealach in Skye, in his famous work 'A Description of the Western Isles of Scotland Circa 1695', first published in 1793, writes of iris roots being dried and ground into a powder for use as snuff to treat headaches and colds. Martin's book was used by Boswell and Johnson during their famous tour of the Western Isles in 1773 and is still in print today.

In Greek mythology Iris was the messenger of the gods, she is also said to have brought the souls of women to the land of Eternal Peace. This could be why they were often planted near graves.

The plant is the origin of an important heraldic symbol, the fleur-de-lis, the use of which dates back into antiquity. Around 1060 it was adopted by the French Kings as a heraldic symbol.  It has featured in the Royal Arms of Scotland, since the time of James I of Scotland (1394-1437).

The plant we know as the Scotch thistle, Onopordum acanthium, is not native. It was most likely introduced from Europe pre-16th century and has now naturalised in many areas. Chosen by Sir Walter Scott (1771-1832) as the emblem for George IV's visit to Scotland in 1822, it has been accepted as a national emblem. The most likely candidate for the true Scotch thistle is the native spear thistle - Cirsium vulgare - abundant in Scotland and very similar to the depictions on early Scottish coins.

The plant has many heraldic connections and is associated with the Order of the Thistle which in the 17th century adopted the wonderful motto, Nemo me impune lacessit (nobody attacks me with impunity) no doubt in reference to the spines.

This ancient order may date to Emperor Charlemagne in the 9th century or, as some suggest, Scotland's James III (1488-1513).

Mary Queen of Scots (1542-1587) had the thistle's image incorporated into the Great Seal of Scotland, making it a national symbol for longevity.

Perhaps the most famous poem about this plant is by Hugh MacDiarmid. Christopher Murray Grieve (1892-1978) who in his masterpiece 'A Drunk Man Looks at a Thistle' (1926) writes the following wonderful lines:

"Rootit on gressless peaks, whar its erect / And jaggy leaves, austerely cauld and dumb / Haud the slow scaly serpent in respect / The Gothic thistle, whar the insects hum"

The following words from the same work are engraved on MacDiarmid's gravestone in Langholm:

"I ha'nae hauf-way hoose, bu aye be whaur / Extremes meet - it is the only way I ken
To dodge the curst conceit o' bein' richt / Tha Dams the vast majority o' men."

Another famous Scot who wrote about its merits was James Scott Skinner (1843-1927) 'the Strathspey King', a traditional fiddler. Born in Banchory, Skinner performed extensively in Britain and America, composing over 600 tunes. Time permitting, he was also a keen gardener. After witnessing his gardener friend Dee Morrison's magnificent thistle display he declared: 'I will compose a tune with the title Dee Morrison's Seven Thistles'. The march is still played on radio and at ceilidhs.

Throughout Britain, Europe and Asia it is found on coastal sand dunes and limestone heath. Next to the thistle, Rosa spinosissima is probably our most emblematic native plant. It has been used as a Scottish emblem since Charles Edward Stuart or 'Bonnie Prince Charlie' (1720-1788) and may have been the source of the Jacobite white cockade.

The Burnet Rose has become a symbol of Scotland, celebrated in song and poetry. Under the pen name Hugh MacDiarmid, Christopher Murray Grieve (1892-1978) wrote these poignant words from 'The Little White Rose':-

"The rose of all the world is not for me.
I want for my part
Only the little white rose of Scotland.
That smells sharp and sweet - and breaks the heart."

This tough reliable rose is the parent of many good garden hybrids which have a strong fragrance. One particularly old variety with double purple-lilac flowers named 'Mary Queen of Scots' is said to have been brought to Scotland by Mary Stuart (1542-1587) from France in 1561.

The Ancient Romans strewed roses over their dead and graves. This resulted in Hecate, Goddess of the underworld, being depicted wearing a rose garland. In early Christianity roses had a mystical quality and were central to ceremonies surrounding birth, marriage and death. In the Islamic world rose water was used to purify the mosque.

Roses also have a long history as an emblem and are regularly seen in heraldry. For example the white rose is the plant badge of the Clan Keith which dates back to the time Malcolm II (died 1034) and the Battle of Barrie in 1010. David I (c.1080-1153) granted the family lands in Lothian in 1150. Later Robert the Bruce (1274-1329) granted the hereditary Marischal Earldom to Sir Robert Keith after the Battle of Bannockburn in 1314.

George Keith, the 4th Earl Marischal (c.1553-1623) founded Marischal college in Aberdeen and negotiated the marriage of James VI to Anne of Denmark. However Earldom and much of the land was lost following the clans support of the Jacobite cause.

The plant is associated with tartan - the small black hips grown each autumn produce juice which provides a peachy dye if used on its own, and a beautiful purple shade when mixed with alum.

Rosa canina is native to Britain, Europe and parts of western Asia. The scented flowers are very variable in colour and have resulted in several cultivated hybrids. These include Rosa canina (Abbotswood) which was found in the garden of Irish engineer, Harry Ferguson, who founded the tractor company which made the famous 'Little Grey Fergie' which changed the face of Scottish agriculture forever.

Robert Burns (1759-1796) also makes over 60 references to it in his many songs and poems as it was clearly one of his favourite flowers.

Shrouded in mythology and strongly linked to the Christian faith, the dog rose is symbolic of purity, love and marriage. It was also linked to the prediction of death, as it was once thought that if you were ill and dreamt of roses you would die!

The bright red hips which are produced in the autumn were once used to make medicinal syrup; they were also thought to give protection from sorcery and witches. This is perhaps why it often features in medieval and gothic architecture and works of art, especially, the wood and stone carving found within ecclesiastical buildings.

On the authority of the Court of the Lord Lyon the rose is recorded in the Public Register of All Arms and Bearings in Scotland and in the Matriculations of Arms of Chiefs as being the official plant badge of the Clans Borthwick, Erskine and Lennox.

Native to Britain, Europe and parts of North America no plant apart from the thistle is more associated with the romance of Scotland than heather. For generations it has featured in our literature, poetry, music and song. Yet few realise that many of the vast expanses of heather that dominate our landscape are the result of deforestation, sheep and the establishment of grouse moors.

Martin Martin (died 1719) a Gaelic factor from Skye famed for his book 'A Description of the Western Isles of Scotland' (1703) discussed the health-restoring qualities of ling when it was used as a mattress.

Osgood Mackenzie (1842-1922) the founder of the famous west coast subtropical garden at Inverwewe also talks about its use in domestic life in his book 'A Hundred Years in the Highlands' (1921) which also explains the establishment of the garden. Evidence exists that heather has been used in brewing in Scotland since 2000 BC and today it is still produced in Argyll and marketed as Fraoch the Gaelic word for the plant.

This brew was celebrated by Robert Louis Stevenson (1850-1894) in his poem:

Heather Ale
From the bonny bells of heather,
They brewed a drink lang syne
Was sweeter than honey
Was stronger than wine.

Bee keepers still take their bees to the heather in the flowering season as the honey produced is extremely sweet with a distinctive taste favoured by many around the world. The foliage and flowers were used to prepare a wide range of coloured dyes ranging from yellow through green to orange and brown. These dyes, and likely the colour of the plant itself have inspired many tartans .

It was also used medicinally. The dried stems are made into besoms and brushes; this was once an important cottage industry in many rural areas. The stems were also bundled and bonded to make floor tiles, similar to the process used to make jewellery today.

White heather is the plant badge of the Clan McPherson who have a clan seat on land granted by Robert the Bruce near Badenoch. The clan was a strong supporter of the crown during the Jacobite uprising.
