This workshop is for those who love Persicaria tincoria and for many who grow them. Michel will explore this indigo plant demonstrating a rare method using dried leaves of Persicaria to start a dye vat. In addition, he will cover how to obtain indigo pigment/dye from fresh Persicaria leaves by water extraction method, and how to make a dye vat with a quick method using the compost form of this plant. Based on the time of year of this event and the timing of Persicaria harvesting, Michel will also discuss how woad can be supplemental as it behaves the same way.
Persicaria tincoria*, previously Polygonum tinctoria is commonly, erroneously called Japanese indigo. It was already in use in the Western Zhou period (1045 – 771 BC) in China and was the most important blue dye in East Asia until the arrival of Indigofera from the south. It is uncertain when the plant reached the Japanese archipelago. There are other indigo plants found growing and being used for blue dye in Japan including Strobilanthes cusia in Okinawa.
