Mimosa as a Southern Illinois Source for Mordant

part of what I feel "my job" is, includes discovering regional resources for natural mordant, printing pigment and dye. To bad I can't go out to a weed or tree read it's label , add to cart, mix with water do a little dance and ta-da natural dyed clothing. Sure once a little familiarity exchange gets going thru experimenting with processing with a particular plant then yes I have a mental label of sorts to reference. {cold no sun 24 degree dec 30th day -honestly so cold it feels like exodus - is a great day to curl up with research and goals]

With nary an umph of want to start an indigo vat, really I don't mind popping out to check on a boiling pot, but the thought of prolonged work in the cold is motivation for discovering a good long steep or ferment.  I have it on deck to clip some mimosa branches for a slow mordant on my cotton tee refashions. I am so itching curious what a mimosa heartwood will contribute to an indigo overdye considering Acacia catechu (Mimosaceae) is recorded to bring forth a lovely gray green when overdyed with indigo. No I'm not that brilliant to have come up with that out of thin air, assuredly I followed a crumb trail to this end.

Facebook group Fermentation in natural dyeing is a worm hole to the universe of natural pigment chemistry {yes practical information way above my serendipitous belief in"a beautiful natural phenomenon will happen"}.  I discovered an in depth research nested in the group files {lots of over my phenomenon practical information} alas a table. I love tables, they remind me of geneology family trees, often a simple layout of who is what . Somewhat of a look see over real good perhaps I know a who on the list before gleaning onward.  Given most  "info"  tables are listed in alphabetical guests, Acacia catechu (Mimosaceae) is at the top of the list. Yes I typical start out totally absorbed in learning at the top of the list and wore out befuddled by midlist. So yes natural dye: acacia /cutch I recognized as first on many lists

Species (Family Name): Acacia catechu (Mimosaceae)   Common name: Cutch tree, Khair  Part used:Heart wood    Colour obtained:   Red   Colour Application: Textile (shipsails, mailbags), Calico printing  ~Table 2: List of natural dyes source and their application, Bhute, Aniket.

The acacia namesake Mimosaceae always intrigues me with regards to beautiful Southern Il evasive Mimosa /Albizia Julibrissin.

The botanical genera Acacia and Albizia are very closely related within the large legume family. Taxonomists place them in the same subfamily, Mimosoideae.

Funny thing most informative mimosa articles include how to eradicate saplings before mimosa invasion occurs. Good heavens blessed be with copious seed and likely birds the mimosa trees are prevalent in Southern Il especially among wetlands. As for me a dear delight wandering forests decorated in whimsy with Dr. Seuss like pink puff  mimosa blooms. A favorite subject from past journaling with my digital art images and I am hoping an excellent regional resource for mordant.

notes...because this is a good place for me to find them again :)

The 1 1/2-inch-wide pink and white flower occurs in a cluster called a corymb on branch tips. 
corymb:  usually flat topped flower cluster in which the individual flower stalks grow upward from various points of the main stem to approximately the same height

Other common names – Mimosa tree, Tree of Joy, Tree of happiness, Pink silk tree, Pink Siris, Lenkoran acacia, bastard tamarind among others.
Latin – Albizzia Julibrussin
Parts used – Leaf, Bark, and Flowers
Constituents – Alkaloids, tetracosanoic acid, triterpenoid saponins, and quercitrin.
[notes : moving these notes forward from oak leaf research]
A flavonol containing many hydroxyl groups, found as its glucoside in plants, including the bark of the American oak Quercus tinctoria.  It is used as a dye.
Chemical dyestuffs:
Quercetin. Colors dyed: light yellow 

Flavonoids Flavonoids are aromatic oxygen containing heterocyclic pigments (i in the epidermal cells of plant parts and are chemically known as 2 of the most widespread groups of natural constituents which are important to man not only because they contrib to plant colour but also because of their physiological activities. They yield yellow dyes which can be classified under flavones, isoflavones, aurones and chalcones. Most of the natural yellows are derivatives of hydroxyl and methoxy substituted flavones and isoflavones. Common example is weld (containing luteolin pigment giving brilliant and fast colours on both wool and silk. Some of the other pigments are Fisetin, Isohamnetin, Quercetin ~Bhute, Aniket. (2012).
