Plants for dyeing: Pokeweed

Pokeweed is shrub that commonly grows in dry, neglected areas. In New England, it generally blossoms in mid-summer and sets fruit in September. Throughout history, pokeweed has had several uses. One of the first plants to show itself in spring, young shoots were gathered, boiled and eaten as a tonic after the long, cold winter. As the plant matures, however, parts of it become poisonous.

The Algonquins called this plant puccoon, which means “plant used for stains or dyes.” An English name for the same plant is “inkberry”, and in my museum classes I sometimes have kids pick, mash, and write with pokeberry. Though technically a berry, which provides a stain rather than a dye, pokeweed can be used to color wool a rich shade of magenta. Unfortunately, stains fade a discolor rather quickly, and are definitely not as colorfast as true dyes. (Think of what happens on that white T shirt that gets blueberry or strawberry stains on it. )

For that reason, I have only used pokeweed to color my yarns a few times. While alum mordant is usually pretty effective with plant dyes, I have not found that it works well at all with pokeweed. My best results and truest, deepest colors have been achieved using white vinegar as mordant.

Pokeweed dyepot:

This is a simple recipe. For a pound of yarn, pick a large paper grocery bag full of pokeweed berries. Crush them until the juice runs, combine with about 1/2 gallon of water in a suitable steel or glass container. Pour in about 1 cup of vinegar. Submerge presoaked yarn skeins into dyebath, raise to a boil, reduce heat and simmer for about 1/2 hour. Allow yarn and dyebath to cool. Rinse yarn in cool water, allow to air dry.

If you try this yourself, I’d love to hear about your results.
