Buying Mimosa hostilis root bark for dyeing
Mimosa hostilis root bark is the tannin-rich root bark of Mimosa tenuiflora, a legume tree of northeastern Brazil and southern Mexico also sold as jurema preta. Natural dyers use it for rose, plum, burgundy and brown on wool and silk, and grey to charcoal with iron. It is sold here by the pound for dyeing and craft, not for human consumption.
Which cut should I buy: powder, shredded or whole?
Buy shredded for everyday dyeing: it strains cleanly and gives second and third baths. Buy powder for test skeins, small batches and soap, because it releases color fastest. Buy whole chips and strips to stock up, because they keep longest and can be broken or milled when needed.
How much root bark do I need for a pound of wool?
Plan on 50 to 75 percent of the dry fiber weight for a mid shade, which is 8 to 12 ounces of bark per pound of wool, and 25 to 40 percent for a pale tint. Deep plum takes up to an equal weight of bark and fiber. A quarter pound is enough to learn on with test skeins.
What colors does Mimosa hostilis give?
On wool and silk it gives dusky rose, plum, red-brown and burgundy, deepening with more bark and a longer simmer. An iron afterbath turns the same bath slate grey to charcoal. Keep the pot neutral to slightly acidic to hold the purple tones; alkaline water pulls it toward brown.
Do I need a mordant?
Not for most wool and silk: the bark is rich in tannins, which help the color bind to protein fiber. Alum brightens the pinks and helps the color hold in daylight. Cotton and linen need a tannin-then-alum mordant to reach good depth, because plant fibers carry no protein.
How is an order placed and shipped?
Choose a cut and a size, from a quarter pound to a full pound, and place your order. A person confirms it and sends payment details in your order chat, then the bark ships from California with tracking. We ship to US addresses only, and parcel orders from 100 dollars ship free.

Guide
Mimosa Hostilis Root Bark: A Dyer's Handbook
Mimosa hostilis root bark is the inner bark of the root of Mimosa tenuiflora, a fast-growing tree of north-eastern Brazil and southern Mexico. Dyers buy it for one reason: it is unusually rich in tannin, and tannin on protein fibre gives purple. It is sold by the pound in three cuts.
GuideHow to Read a Certificate of Analysis for Root Bark
Check four things in this order: does the batch code on the report match the bag in your hand, when was it tested, is the laboratory accredited for those tests, and does the report cover species identity and contaminants such as heavy metals and microbes. A report that fails the first check describes different material.

Questions people ask
All questionsWhat is Mimosa hostilis root bark used for?
It is sold as raw botanical material for natural dyeing, soap color, leather work and craft. Dyers use it for rose, plum, burgundy and brown on wool and silk, and grey to charcoal with an iron afterbath. It is not food and it is not for human consumption; at checkout you confirm that is what you are buying it for, and that confirmation is stored with your order.
Should I buy powder, shredded or whole root bark?
Shredded for everyday dyeing: it strains cleanly and gives second and third baths from the same bark. Powder for test skeins, small batches and cold-process soap, because it releases color fastest. Whole chips and strips for stocking up, because they keep longest and can be broken or milled when you need them.
How much Mimosa hostilis do I need to dye a pound of wool?
Plan on 50 to 75 percent of the dry fiber weight for a mid shade, which is 8 to 12 ounces of bark per pound of wool, or 25 to 40 percent for a pale tint. Deep plum and burgundy take up to an equal weight of bark and fiber. Test a small skein first, because water and fiber change the result.
Do you offer bulk or wholesale pricing?
Yes. Root bark is priced by the pound in 1/4, 1/3, 1/2 and 1 lb sizes, and larger quantities for dye studios, soap makers, schools and resellers are quoted by a person. Use the bulk order page or email sales@mimosalsd.com with the cut and the quantity you need.
