St. Johns Wort Plant Collecting and Dye Bath

St. John's Wort (hypericum perforatum) yellow star shaped flowers, are found along grass verges. These photos are from the Tarka Cycle Trail old rail track - Barnstaple to Bideford; my 10 mile route for foraging, using Jenny Dean's plant spotter book.

Dye Bath  - 1st Soak

  • Soak flower tops overnight in rain water. I use pond water.
  • Boil up and simmer for an hour
  • Cool liquid until hand hot, not to roughen silk, soak silk, stirring occasionally.
  • Leave overnight to absorb dye colour

Dye Bath  - 2nd Soak

  • Second silk piece added on top through the night.
  • 2nd day: Remove first stronger dyed silk piece and rinse out, not squeezed too much and leave to dry.
  • Drain seeds and flowers and heat remaining paler dye bath. Add second piece again for half a day.
  • Rinse out when water completely clear. Colour was blotchy, so I cut it in half.

Dye Bath  - Session Two - Iron

Iron Modifer: Olive Green-Khaki Results

I heated dye bath again, allowed to cool, before adding tablespoon of ferrous sulphate for third final piece of silk. (for khaki colour) Silk must not be exposed too long to iron mix as can weaken it. Colour change is immediate so 5 mins sufficient; less to just dull colour.  Rinse out with a little soap.

  • Silk dyed with no mordant = GOLD.
  • Silk modified after dyeing with iron = KHAKI
  • All cream and gold dyed silks with any plant dyes will turn  duller, khaki, or grey after a dip in iron.

Notebook:  I bought the iron (ferrous sulphate) specially, but you can make your own. I generally experiment with adding water from a jar of rusty nails and screws; about half a tea cup to turn grey or khaki. Top up jar as rusty liquid is used. Even a spoonful dulls a colour adequately.

Comfrey dyed silk

Amelia Hoskins / Dyes, Plant Dye / / 0 Comments

Comfrey dye bath makes an ecru cream-beige, which becomes duller and darker after dipping in iron modifier, after dyeing.

This sample experimented with shibori stitching prior to dyeing which resulted in several vey pale wavy lines of resist made by where the stitching gathered the cloth to prevent dye entering.

Result after dyeing shows Shibori stitch-resist as pale wavy lines. (Stitches are removed after full dye process.) The idea to make ‘waves’ by stitching in ‘curves’ worked, but contrasts poorly on pale colours. Large pegged sample shows dye-bath original tone at bottom right, and darker result top left, after adding iron modified. (black marks are the iron water splashed as I poured in iron solution, so take care with fabric proximity)

Preparing dye-bath with comfrey leaves

Cut up comfrey leaves and soak overnight. Also soak silk in alum mordant overnight or for some hours beforehand. Silk often dyes well without mordant when using some plants. Lighter colour at left, darker tone after longer soaking. Best to leave soaking over night to ensure good dye absorption. New pieces can be dyed in dyebath afterwards, and will be paler, but always a good starter colour for painting, or re-dyeing over.

Boil up and simmer for an hour. When just hand hot, drain comfrey out and put dye liquid in a bowl to soak the silk. (I never boil this ahimsa silk as it becomes matted in high temperatures) Agitate to distribute dye equally for first 15 mins, then leave to soak all day, redistributing in dye occasionally to ensure even dyeing.

Dyed and washed out, the ahimsa silk has an ecru beige colouring where first dyed (top left) – with additional dulled, more grey colour where half of cloth was soaked into iron modified dye bath. Out of the sunlight, the iron modified sample is quite dull and darker, to be used as one would a grey.

Sample (gallery top right) compares comfrey colour dye result with Ladies’ Bedstraw, peach. Samples (gallery bottom right) show iron modified comfrey sample in centre; between (left) Hawthorne dyed silk (left) and natural, ecru result of non-modified comfrey dyed silk in second dye bath. (right).

Note: A second dye-bath was made by reboiling liquid and leaves leaving overnight to stand. Heated next day, added fresh un-mordanted silk. Left to soak for a day and overnight 24hrs. This produced a pale but warm ecru silk.

Below: Comfrey dyed silk in centre – dull tone is result of iron modifier. Silks look duller indoors whereas they come to life in sunlight. The range of colours obtainable is fascinating.

Conclusion: Comfrey gives a very good neutral tone suitable for use with any silk painting over. Longer steep in iron (ferrous sulphate) would make it greyer, as needed. Experiment with quantities of iron added. I use either water from a rusty-nails-jar as well as purchased powder.

This piece will be silk painted over in a design, to become part of a garment in due course… updates will be posted here with link to the garment in making.

Ladies bedstraw Dyed Silk

Roots dug out and flower tops

Lady's Bedstraw is found in waste ground or unused areas and near the coast.  This particularly large and well established plant rambled on the River Torridge embankment above the Bideford marshes along the Tarka Trail cycle path (N. Devon).   The reddish roots are used for dyeing: family is Madder (Rubiaceae) a well known red dye. Not easy to pull out the roots, and most were left for next year's growth.  It was immediately apparent why it is called 'bedstraw' as plant sprigs were 'springy' in the hand, making it ideal for mattresses.  Bedstraw has many herbal uses too.

Soak roots in water for many days

Roots taken from plant ground need soaking for several days to soften, before boiling up. (I soaked mine at least a week).

Roots of plant produces a red dye, the longer soaked the deeper red. The red dye appears while soaking, and would probably dye without even boiling up.  Photos show the dye was absorbed onto the pan sides, which I believe lost dye pigment strength available; so pans must preferably be steel. Copper pot might also assist with tan tone.

Silk is soaked in dissolved alum

Some dyes will work without soaking cloth in a premordant.  I usually do two tests. The second piece was not mordanted, and is some shades lighter on drying, but probably only because the first piece absorbed most of the pigment.

Steam press silk before bone dry to reduce creases. (don't squeeze out too tightly). The patchy areas do not show in the final dried sample.
