Natural Dyeing: Ochre From Green


cotton dyed with helenium flowers and purple loosestrife leaves

I like to dabble in natural dyeing; that is, trying to dye fabric with colours derived from plants.

To make things even harder for myself I use cotton material. It would be easier to use wool because the colour chemicals bind better to protein than the cellulose of cotton, but I prefer to sew rather than to knit, so if anything is going to be made from the colour experiments it has to be sewable.

This quilted wall hanging thingy was made using all sorts of leaves from the local park.

Recently I read you can get a colour from helenium flowers and purple loosestrife - two plants that fortuitously grow in Garden65, so of course I had to have a go.

First the plants are simmered for half an hour or so, then they are strained out and the fabric put in the 'dye bath' and again simmered for half an hour or more.

You would think the yellow flowers would create the better colour, but I was blown away by the deep ochre colour the plain green leaves of loosestrife produced.

The queen of natural dyeing is India Flint. Have a butcher's at her site to see how it should really be done.
