Title: Plants for making dyes for organic cotton
Answered by: Nan Hampton

QUESTION:

Looking to dye my own organic cotton for my new line of organic clothing and I want to grow the plants for making the dyes in my own garden. Any suggestions?

ANSWER:

Delena Tull in her book, Edible and Useful Plants of Texas and the Southwest: A Practical Guide (University of Texas Press, 1999) has an excellent section called "Colorful Dyes with Texas Plants" in which she lists notable Texas dye plants along with an indication of the brilliance of the color and resistance to fading. She also has information about whether the dye needs a mordant and, especially important, whether the plant has toxic qualities that you need to be aware of. Most of the plants she lists are Texas natives, but she does list some non-natives (e.g., Common mullein (Verbascum thapsus)) that have been introduced and are now commonly found in the state. You can check the nativity of the plants she lists by searching in our Native Plants Database or the USDA Plants Database. Here is a short list of some of the plants she lists that do well in the Austin area:

Prickly pear (Opuntia engelmannii) red, magenta, or tan depending on dyeing method
Turk's cap (Malvaviscus arboreus) peach, mauve, or tan depending on dyeing method and mordant
Agarita (Mahonia trifoliolata syn. Berberis trifoliolata) yields yellow to yellow-orange
Bitterweed (Tetraneuris scaposa syn. Hymenoxys scaposa) yellow dye
Bluebonnet (Lupinus texensis) light lime green
Old man’s beard (Clematis drummondii) golden brown, brown or yellow depending on the plant part used
Goldenrod (Solidago spp.) a range of colors from yellow, orange, tan, olive and gray depending on the plant part and mordant used
Greenbriar (Smilax bona-nox) grays, greens, yellows, and reds depending the plant part and mordant used
Pokeweed (Phytolacca americana) pink, orange, red, blue and black depending on mordant and dyeing method

These are only a few of the plants listed in the book. Many trees (such as oaks, pecans, and walnuts) that grow in Austin have material that make good dyes as well.
