Japanese Indigo / Dyer's Knotweed [Persicaria Tinctoria]

An ancient and iconic source of blue. It has long leafy stems that can be easily propagated, and produces beautiful pink flowers in Autumn. Yields beautiful blues through a vat dipping process. Can be used for fresh leaf dyeing or for fermenting and extracting pigment.



Indigo is not only a great source of natural colour that you harvest and then infuse into your house and wardrobe, but are also beautiful colourful/sculptural additions when in flower, attracting bees and other pollinators.
