CHAPTER IV.
BRITISH DYE PLANTS
The introduction of foreign dye woods and other dyes during the 17th and 18th centuries rapidly displaced the native dye plants, except in certain out of the way places such as the Highlands and parts of Ireland. Some of these British dye plants had been used from early historical times for dyeing. Some few are still in use in commercial dye work (pear, sloe, and a few others); but their disuse was practically completed during the 19th century when the chemical dyes ousted them from the market.
The majority of these plants are not very important as dyes, and could not probably now be collected in sufficient quantities. Some few however are important, such as woad, weld, heather, walnut, alder, oak, some lichens; and many of the less important ones would produce valuable colours if experiments were made with the right mordants. Those which have been in use in the Highlands are most of them good dyes. Among these are Ladies Bedstraw, whortleberry, yellow iris, bracken, bramble, meadow sweet, alder, heather and many others. The yellow dyes are the most plentiful, and many of these are good fast colours. Practically no good red, in quantity, is obtainable. Madder is the only reliable red dye among plants, and that is no longer indigenous in England. Most of the dye plants require a preparation of the material to be dyed, with alum, or some other mordant, but a few, such as Barberry, and some of the lichens, are substantive dyes, and require no mordant.

FOOTNOTES:
[2] "On boiling sloes, their juice becomes red, and the red dye which it imparts to linen changes, when washed with soap, into a bluish colour, which is permanent."
[3] "For giving very inferior yellow upon coarser woollens, the dyer's broom, _genista tinctoria_, is sometimes employed, with the common preparation of alum and tartar."
[4] Sawwort which grows abundantly in meadows affords a very fine pure yellow with alum mordant, which greatly resembles weld yellow. It is extremely permanent.
[5] "The leaves of the sweet willow, _salix pentandra_, gathered at the end of August and dried in the shade, afford, if boiled with about one thirtieth potash, a fine yellow colour to wool, silk and thread, with alum basis. All the 5 species of Erica or heath growing on this island are capable of affording yellows much like those from the dyer's broom; also the bark and shoots of the Lombardy poplar, _populus pyramidalis_. The three leaved hellebore, _helleborus trifolius_, for dyeing wool yellow is used in Canada. The seeds of the purple trefoil, lucerne, and fenugreek, the flowers of the French marigold, the chamomile, _antemis tinctoria_, the ash, _fraxinus excelsior_, fumitory, _fumaria officinalis_, dye wool yellow." "The American golden rod, _solidago canadensis_, affords a very beautiful yellow to wool, silk and cotton upon an aluminous basis."--Bancroft.
