Applications
Fabric Dyeing
Mimosa Hostilis root bark can produce purple, mauve, and burgundy-leaning shades on natural fibers. Fiber preparation, mordant choice, water, and dye method affect the final color and wash performance.
Artisan Soap Making
The fine Mimosa Hostilis powder blends smoothly into cold-process and hot-process soap batter, producing beautiful pink, mauve, and purple hues without synthetic colorants. Color develops and deepens naturally during the cure.
A Centuries-Old Tradition of Natural Color
Known as Tepezcohuite in Mexico, Mimosa Hostilis (Mimosa tenuiflora) root bark has a history of use in botanical craft. Its tannin content can contribute purple, mauve, and burgundy-leaning shades, with results varying by fiber and process.
Today, fabric dyers and artisan soap makers use Mimosa Hostilis root bark as a botanical colorant. Results depend on material, fiber, mordant, water, and process.

Frequently Asked Questions
What is Mimosa Hostilis root bark used for?
Mimosa Hostilis root bark (known as Tepezcohuite in Mexico, botanical name Mimosa tenuiflora) is primarily used for natural fabric dyeing — producing beautiful shades of purple, mauve, and burgundy on cotton, wool, silk, and linen — and as a natural colorant in artisan soap making. It's also used in leather tanning and natural cosmetics, though fabric dyeing and soap making are by far its most popular craft applications.
What colors can I achieve with Mimosa Hostilis root bark dye?
Depending on the mordant, fiber, pH, extraction time, water chemistry, and natural batch variation, you can achieve colors from soft pink and mauve to deep purple and burgundy. Alum preserves and brightens mauve, pink, and purple; iron shifts toward gray-plum, charcoal, and near-black; and copper shifts toward olive and teal. Powder, shredded bark, and chips offer the same base color spectrum—the form changes extraction speed, bath concentration, sediment, and straining.
Which form should I choose — powder, shredded, or chips?
For a first fabric-dyeing project, choose shredded bark because it extracts steadily and is easy to strain. Powder extracts fastest and disperses evenly in soap batter, but its fine sediment needs careful straining in a dye bath. Chips are best for slow-steep dye baths and traditional preparation methods. All three forms can produce the same base color spectrum.
How do I prepare a natural dye bath with Mimosa Hostilis root bark?
Soak the bark in water overnight, then simmer (don't boil) for 1–2 hours. Strain the liquid to create your dye bath. For best results with fabric, pre-mordant your fibers with alum or another natural mordant before dyeing. The weight of dye material should be 50–100% of the weight of your dry fabric for rich color.
Is Mimosa Hostilis root bark legal to purchase for craft use?
Yes, Mimosa Hostilis root bark is generally legal to purchase in the United States for natural dyeing, soap making, and botanical craft. Laws and regulations can vary by location and intended use, so confirm the rules that apply where you live.
How should I store Mimosa Hostilis root bark?
Store in a cool, dry place away from direct sunlight. Keep in an airtight container to maintain freshness and potency. Properly stored, the bark will retain its dye properties for years. The powder form is slightly more sensitive to moisture, so extra care should be taken to keep it dry.
