I read in the book Eco Colour: Botanical Dyes for Beautiful Textiles by India Flint that the leaves of garden sage make a red dye. This intrigued me and since I have several very robust Salvia officinalis plants, I decided to try it. I believe this must be a misprint. It is more than likely that the purple flowers will yield a red dye. I will try that next June. In the meantime I am very pleased with the sage green I got from these leaves.

I simmered some of the used dye bath until it was reduced to half. The color is very dark. I believe this will make a wonderful ink.
