First thing’s first. If you have your heart set on using a wild dye plant not listed below, please buy your wild dye plants from a native plant supplier. For example, DO NOT harvest Wild Indigo for dye use from the wild. There are many ways to cultivate and grow these wild crops. You can still label them as native plant dyes, even though they were cultivated, and still fill a niche market.
There are so many available plant dyes in this Muskoka and Haliburton territory we call home. The flowers, berries, nuts, bark, roots, stems, and leaves listed below are all useable and reasonably sustainable. All we need to do is notice when these plants and their parts become available for use and respect each plant’s ability to reproduce the parts you are using.
Several of the dye plants that I’ve researched produce a great dye, but because of their nature, they are at risk for exhaustion from over harvesting, so I’m only going to discuss plants that are very commonly found, plants that can be classified as weeds, and some that are even invasive.
The dark inks used in this Buwalda drawing on watercolour paper were created using the husk of Black Walnut and Purple Loosetrife pulled from a client’s wetland.
When you are gathering plant material for dyeing, the blossoms should be in full bloom, berries ripe, and nuts mature. Remember, never gather more than 10% of a stand of anything in the wild when gathering plant stuff for dyeing. If you are using tree bark, only harvest from plant parts that have separated from the living specimen, ie. Branches downed from a storm or bark from a fallen tree that is still sitting on the ground and separated from the heartwood and cambium that has long begun to rot. You must take the opportunities as you happen upon these offerings rather than seeking them out.
When we gather plants to create a dye, we also need to remember how much bulk of the plant is actually required to dye a batch of fabric. It is very important to keep in mind that if the chemical mixture you are creating will permeate a fibre and will permanently change the colour, the liquid is a concentrate and should be treated as a toxin, even without the mordant. All dye projects should be considered as a chemistry experiment and one needs to behave as they would in a lab. Taking notes is a great habit that will improve future results.
Some will pre-treat a fabric with a mordant (colour fixative) and rinse it well before adding the fabric to the dye solution, while others will add the mordant to the dye solution.
Some will create a dye with plant material, strain it, and then add the fabric, while others will mix the fabric in with the plant material in layers, like a lasagna. It really depends on how dark you want the dye and what process works with each mordant and each plant material.
One can also create differences in a specific plant dye by allowing the plant to decompose and almost ferment. We’ve done this with Black Walnut.
To get the fibre or fabric ready for the dye bath you will have to soak the fabric in a color fixative before the dye process. This will assist the color set within the fabric.
The most common mordants are:
- Cream of tartar, iron, tin, alum or chrome (these are available from dye supply shops, or your local pharmacy).
- Salt Fixative (for berry dyes) 1/2 cup salt to 8 cups cold water
- Plant Fixatives (for plant dyes) 4 parts cold water to 1 part vinegar
You could also try making natural mordants from plant material to have a completely plant-based product.
- Staghorn Sumac (Rhus typhina)
The leaves of sumac are high in tannin which can be used in the process of mordanting plant fibres like hemp and cotton. Sumac is also used in treating leather.
Some people can have an allergic reaction to sumac so always wear gloves when prepping any plant-based solution concentrate.
Use 40 grams dry leaves and shoots (so about 40 complete compound leaves snapped off of the branch at the base of the petiole) or 80 grams (about 40) fresh leaves and shoots per 100 grams of cotton.
- Rhubarb (Rheum spp) as a mordant
The liquor from boiled rhubarb leaves is used in Tibet as natural mordant that works best with animal fibres.
How to turn Rhubarb leaves into a natural dye mordant
One pound of rhubarb leaves can mordant several pounds of fibre. Boil the leaves for an hour to extract the tannin. Make sure you boil the leaves in a well-ventilated area, as the fumes will be toxic. Rhubarb leaves contain oxalic acid, which is a poison, and should never be eaten.
- Juniper (Juniperus communis) as a mordant
Gather green Juniper boughs and burn them clean, without any other materials. This is best done above a grate, then you can gather the ashes from under the grate and use them as a mordant instead of alum. Ashes and water form a natural lye, which is alkaline and can cause burns if not used with care.

Basic How-to-Make a dye solution:
Chop plant material into small pieces and place in a pot. Double the amount of water to plant material. Bring to a boil, then simmer for about an hour. Strain. Now you can add your fabric to be dyed. For a stronger shade, allow material to soak in the dye overnight.
Getting the fabric ready for the dye bath: You will have to soak the fabric in a color fixative before the dye process. This will make the color set in the fabric.
Most Common Color Fixatives (Mordants):
Salt Fixative (for berry dyes) 1/2 cup salt to 8 cups cold water
Plant Fixatives (for plant dyes) 4 parts cold water to 1 part vinegar (much easier than Rhubarb)
Other Mordant: Cream of tartar, iron, tin, alum or chrome
Add fabric to the fixative and simmer for an hour. Rinse the material and squeeze out excess. Rinse in cool water until water runs clear.
Dye Bath: Place wet fabric in dye bath. Simmer together until desired color is obtained (remember though that wool does not like to boil so keep it at 80 degrees). The color of the fabric will be lighter when its dry. Also note that all dyed fabric should be laundered in cold water and separately.
Muslin, silk, cotton and wool work best for natural dyes and the lighter the fabric in color, the better. White or pastel colors work the best.
It’s best to use a retired large pot as your dye vessel.
Wear rubber gloves to handle the fabric that has been dyed, the dye can stain your hands.
When using mordants and concentrated solutions it is best to wear safety eyewear. Do not breathe in any of the steam.
It’s also important to note, some plant dyes may be toxic, check with the Poison Control Center if unsure. Again, make sure that the pots and other tools you use for mordanting and dyeing are only for dyeing not for cooking
You will be cooking plant concentrates and mixing plants with chemical compounds under hot to boiling conditions. Work in a spotless and uncluttered workspace and keep away from children and pets.
