Lady’s Bedstraw is found in waste ground and near the coast. The reddish roots are used for dyeing; family is Madder (Rubiaceae) a well known red dye. The plant I found is growing along the Tarka Trail cycle path (ex rail track) opposite the small town of Bideford, N. Devon. Not easy to pull out the roots, and many were left for next year’s growth. This seemed a particularly large and well established plant. Bedstraw has many herbal uses.
Lady’s Bedstraw Ahimsa silk results: 1st soak strong peach – 2nd soak light peach.
Dye bath procedure
Roots need soaking for several days to soften, before boiling up.
Boiling roots of plant produces a red dye, the longer soaked the deeper red. Photos show the dye was absorbed onto the pan sides, which loses dye power available, so pan must be aluminium. Predicted colour is scarlet, so use stainless steel.
1st silk sample has been pre-mordanted in Alum for a day before putting to soak in hand hot dye bath. Rinse away plant debris and extra dye: result after rinsing and drying is a strong salmon hued peach colour.
1st silk sample Rinsed. Has been already soaked in dye bath one day. 2nd silk sample in cooled dye bath which was reheated with bedstraw to obtain more dyestuff.
Red dye liquid is drained off into glass bowl to soak silk.
1st silk sample: Strong peach result after washing out. Steam iron while still damp to help smooth out creases, or don’t squeeze out water.
2nd silk sample Rinsed. Result when dry is a light peach.

These samples will be matched with recycled fabric prints, and painted on before becoming part of a new garment.
