harvesting colour – the orange of alder bark
Last week we went out to our cabin lot to collect some material for my dyeing experiments. We are constantly battling the alders which move in quickly after any clearing. I think my husband was quite agreeable to cutting some alder sticks for me to use as dyestuff. Our alder is Alnus rugosa (Du Roi) Spreng, the speckled alder.

Yesterday, I sat on our deck to peel the bark from the alder sticks. I was acclimatized to the orange dye I expected from the alders by the leavings of last autumn – the piles of dry maple leaves still on the deck and the bright sienna of my terra cotta pots.
The alders peel easily, revealing a bright green inner bark. The green quickly oxidizes to a bright orange, due to the presence of the chemical oregonin. By the end of the debarking session, my jean were stained dark orange and my palms of my hands were covered in the colour of tangerines.

I was glad to have moved my dyeing adventures out to the back deck because the smell was quite acrid. As I boiled the bark, the water became a dark orange.

I simmered my length of alum-treated wool roving in the liquid for about an hour.

Although it is not orange, the colour is a pleasing yellowish-brown, similar to but more yellow than the colour obtained from Old Man’s Beard lichen.

Now that the warm weather is here, I am looking forward to more hours on the deck, watching over my concoctions and seeing more colours emerge!!!
