Informative first. We publish what we can verify and cite what we rely on.
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.
GuideHow to Order Root Bark Here, and How Payment Works
You order here by sending a request, not a payment. A person checks the stock and your address, then sends payment details in your order chat and by email for the method you chose: Cash App, Chime, Apple Cash or Bitcoin. Once payment arrives, the bark is weighed, nitrogen-sealed and shipped from California with tracking.
Questions people ask
All questionsDo you ship to my state?
Yes. We ship to every US state and the District of Columbia, and your cart shows the delivery option and cost for your address before you order.
When do I pay for my order?
After a person has confirmed it. You place your order and choose a payment method; we check the stock and the address it is going to, then send payment details in your order chat on this site and by email. Your order is confirmed once payment arrives. We never ask for card details.
How old do I have to be to order?
You must be 21 or older. You confirm your age once, when you enter the site, and everything we sell is for adults 21 and over, whatever the product.
What 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.
How much is delivery?
Standard parcel delivery is $7.95, and free on parcel orders over $100. We confirm a delivery window with your order rather than publishing one, because it depends on the carrier and how far the parcel travels from California.
