HEATHER DYE ~ Dye Colour yellow and green
Heather blooms in late Summer here in Ireland, covering our green hills in a blanket of purple, pink and white. Heather was traditionally used to dye wool and tweed yellow and green brown.
The Flowers by themselves will give clearer yellows and greens with Iron. The whole Heather plant, due to the tannin in the wood, creates deeper golden yellows and green browns with iron.
