Japanese Indigo is also know as Chinese Indigo, or Dyer's Knotweed.
The Japanese refer to it as "Ai." For centuries, Japanese Indigo has
been widely used in Asia as a source for blue dye. The leaves of this
plant contain indican, a glucose substance, which once reduced (made
soluble), results in beautiful shades of blue and aqua on both protein
(animal) and cellulose (plant) fibers.
More detailed information about growing Japanese Indigo and how to prepare an indigo dye bath may be found on the Japanese Indigo - 2011 post. Here I will just share my latest exploits in dyeing with this plant on wool, silk, and linen.

ReplyDeleteThank you, India. You are such an inspiration! I hope to plant a eucalyptus tree in my yard this spring and begin experimenting with eco-prints on cloth. I have been gathering rusty metal objects for some time! --Pallas
ReplyDeleteHow original! Your content is very knowledgeable. I was trying to find appropriate material and here I got bundle of information On Linen Shirt. This is first rate work.
ReplyDeleteJustlinen, I appreciate your comments. I began this blog simply as a notebook for myself, a place to store information on how I created my dye baths and what plants yielded which colors. Then others started to find my blog and have shared that it has been very helpful to them as natural dyers to find detailed information on HOW to do it. Your clothing line looks very interesting! --Pallas
