Applications
Fabric Dyeing
Mimosa Hostilis root bark produces vibrant shades of purple, mauve, and burgundy on cotton, linen, silk, and wool. The tannin-rich bark acts as its own mordant for long-lasting, wash-fast color. Works beautifully for yardage dyeing, tie-dye, shibori, and fiber arts.
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 its native Mexico, Mimosa Hostilis (Mimosa tenuiflora) root bark has been prized for centuries as a natural botanical dye and skincare ingredient in traditional Mexican craft. The inner bark is exceptionally rich in tannins that produce stunning shades of purple, mauve, and deep burgundy on cotton, linen, wool, and silk.

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 used and the fiber type, you can achieve a range of colors from soft pink and mauve to deep purple and burgundy. Alum mordant produces lighter mauve tones, while iron mordant deepens the color to rich plum and near-black shades. The powder form gives the most intense color, while chips provide more subtle, controlled results.
Which form should I choose — powder, shredded, or chips?
Powder is best for maximum color release and even distribution in soap batter. Shredded bark is ideal for dye baths where you want good color release with easy straining. Chips are perfect for slow-steep dye baths and traditional preparation methods. Many dyers keep all three forms on hand for different projects.
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 legal to purchase in the United States for craft applications including fabric dyeing, soap making, and botanical formulation. It is a botanical product sold exclusively for legitimate craft purposes.
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.
