Callistemon spp., Rince-bouteille, Zylinderputzer, Cepillo, Scuab bhuidéal

On the way to the station I noticed a whole bundle of dry bottlebrush stamens that had gathered in the gutter after a windy day or two. On the way back that very afternoon I scooped them up and trotted off home with the intention of seeing how wool would take any colour they had to offer.

Experience, let alone all the sources available, has taught me that red won’t yield red, and if it does, it’ll soon fade. In Dyemaking with Australian Flora, results are given for the leaves and fruits of various species, but not the flowers. However, after simmering the plant material, straining then adding the yarn, it was clear that some result would be obtained. I persevered…

The final results were worthwhile, giving shades of brown and gold. Only problem was, I couldn’t remember which order I’d hurriedly stashed them (mordanted/non-mordanted) to do other things before writing this entry… Drawing on experience, the alum/CoT mordant gave yellower shades, the alkaline modfier deepended these, the acid modifier didn’t make much difference, although I think (or perhaps am imagining) a slightly redder shade, whilst the iron modifier clearly deepened the shades as expected without “blackening”. There’s also none of the potentially resulting harshness.

From left to right: 1, 3, 5, 7 no mordant; 2, 4, 6, 8 alum/CoT, 3 + 4 alk modifier, 5 + 6 acid modifier, 7 + 8 iron modifier. The colours in real life are deeper.

Would I dye with bottlebrush again? Sure, if enough material could be found again. Callistemons are used as street trees in a lot of suburbs, so they’re not exactly rare or endangered. However, usually the stamens just blow off individually and don’t amass, so looks like I was lucky.
