Indigenous herbaceous plants Our embankments, woods and meadows harbour numerous interesting plants used for dyeing. Here are just a few examples that you can gather yourselves when out for a walk. Broad-leaf dock dye with iron mordanting is one of the traditional recipes for obtaining black in Ireland and Scotland. Bedstraw, like madder, belongs to the Rubiaceae family (from the Latin rubia, red) and produces red dyes, as do the petals of poppies and St-John’s-Wort. Nettles are forgiven for stinging by yielding lovely yellows, as do meadow clover, dyer’s camomile, solidago and mugwort. The finest, most stable yellow dyes come from dyer’s savory and dyer’s weed. The blue from cornflowers is used in illuminated manuscripts. Plant dyeing is an art that has evolved over thousands of years of practice, experience and learning. An art based on knowledge of these plants that produce substances which can be used to dye fibres. This garden takes you into the magical world of natural colour to propose a new approach to Mother Nature’s riches, a different view of these small, insignificant plants, some of which have changed history and the world’s appearance. The plants presented in this garden have been used by generations of artists, dyers and colourists to add hues of red, blue and yellow, a rainbow of colours, to precious tapestries, brocades, silks and cottons, some of which have kept their colours unfaded down the centuries. These techniques, the only source of textile colours until the 19th century, have now been replaced by synthetic products. And yet this know-how proves indispensable when restoring the ancient works that are part of our cultural heritage or to offer the artists of today materials that will remain intact tomorrow. Aquatic and water’s edge plants A number of the plants capable of living with their feet in water are good sources of black, such as the white water-lily, the yellow iris, the willow and the queen-of-themeadow. The latter two plants also have medicinal properties and contain active ingredients on which aspirin is based. Some reeds are traditionally used in Japan to dye fabrics yellow. 3 Garden of Colour Plants Garden of Colour Plants 10 Plants used in dyeing have a history rich in anecdotes that are sure to surprise you. They have on occasion influenced our own history, arousing the covetousness of men, fascinating generations of dyers, leaving their mark on the world. Dyeing is an art that calls for knowledge. To ensure that the colour lasts, various techniques are used to reinforce the dye itself, including washing the fibres beforehand in soda, amongst other things, or mordanting which fixes the dyes in the fibres. This is often done with alum, iron sulphate or copper sulphate. Some plants require special preparations before they can be used. Pastel leaves, for instance, have to be chopped, crushed and left to ferment and then formed into pellets known as “cocagnes”, a term also used to refer to a mythical land of plenty, the Land of Cockaigne. Garden of Colour Plants 4 e garden of colour plants Yes, that’s right, vegetables play with colour, too. During the Second World War, girls used the brownish juice from the roots of roasted chicory to colour their legs, instead of wearing nylon stockings. Onion skins are used to colour eggs at Easter. And several of the plants found in a vegetable garden can dye fabrics permanently. The rhizome in rhubarb produces varying shades of orange that are resistant to light and to washing. In Tibet, rhubarb is the main source of the yellow and orange dyes used for Tibetan carpets. Indigenous woody plants Garden of Colour Plants 8 Several of our indigenous woody plants can be found in this garden, in the tubs behind the arbour but also in the embankment along the plot. Blueberries were used as early as in Gallic times to dye fabrics purplish blue, as were the berries of the elder, ivy or privet. These, along with juniper berries, are among the rare dyes mentioned from the 16th century onwards as producing green in a single dip, after mordanting with alum or copper. Dyers in the 19th century even endeavoured to promote their use to dye cotton and silk. Barberry and dyer’s broom produce yellow shades, as does purging buckthorn, also known as the “Avignon berry”. This, along with dyers’ weed and solidago, were among the plants used to dye yellow the rouelle or badge, and the pointed hats which Jews were required by the papacy to wear as an identifying mark from the 13th century onwards. The garden itself contains over 130 colour plants. A first. To make the garden clearer, the plants are arranged by theme. Why not come and find out about some of them, to give you a foretaste of the diversity of this collection. Mediterranean and exotic plants The first set of plants used in dyeing carries you to Mediterranean climes. Here you will find a number of stars in the world of colour, including henna, the indigo plant from the Indies, safflower, madder, Chinese indigo or pastel, as well as others that are less well known, such the Judas tree, the common pokeberry or the strawberry tree. Some are better known for their use as food, such as the passion flower, the fig tree or sorghum. And yet, did you know that thyme dyes fabrics orange and oregano purple? Ornamental plants 5 Several of the decorative flowers and shrubs commonly found in our gardens provide superb dyes. For instance, the petals of the deep purple hollyhock produce violet to purplish blue shades. In the 19th century, this was used industrially in Germany to dye cotton fabrics. It is also a food colorant, used amongst other things to enhance the colour of red wines. Marigolds, dahlias and coreopsis provide orange, as does the famous saffron. This costly spice, extracted from the stamens of the crocus, is used to colour paella, but also the robes of Buddhist monks.
