I watched both sessions of the Baltimore Natural Dye Symposium last weekend, put on in conjunction with the Maryland Institute College of Art Fiber Department. The first was "Indigo Shade Map" https://youtu.be/z-BdjM0PAfA featuring Gasali Adeyemo, Brittany Boles, Wang Sik Kim, and Kenya Miles, moderated by Rosa Sungji Chang. The second, and the one I was very inspired by was "Korean Natural Dyes: Traditions Meet the Contemporary and Beyond" https://www.youtube.com/watch?v=ukw2DwscCQg featuring Dr. Heo, Buk Gu, Prof. Cho, Mi Sook, Kindigo, and Aimee Lee, moderated by Rosa Sungji Chang. Though indigo was the focus of both sessions, after watching the Korean Natural Dye session, a link left in the chat to a Korean artist, Yang Soon Ja, who dyes with persimmon http://www.jejucatalyst.com/479-2/ put me on to dyeing with mugwort (Ssuk). I have three bushes growing in my garden-though I think it is a different type of Artemisia (artemisia vulgaris) than is used in Korea.
I got this light, silvery green sage color, which is quite pretty. I want to use more mugwort next time to get a bit more of a saturated sage color.
