Red is the challenge for my backyard foraging. So, this is a cheat since I foraged this dye in my grocery store!!
Dried achiote or annatto seeds are sold in the Mexican section of my store. The color is a lovely golden orangey-yellow. But there’s a turpentine-like smell when it heats. NIce color, bad smell.
And, this was a big surprise. I love ornamental grass. It’s carefree and looks good throughout the year. To say that there’s not much color is an understatement. I picked the “seed heads” from some pennisetum alopecuroides. Looking closely at them, I can see that the small tips are a bit purple. But, they look off-white/tan. When I dyed with them, I got the same green that I observed in Fountain Grass.
