It's one of those unusual anomalies that sometimes happen. We know that boiling willow bark turns the fibres red but sometimes you don't even have to boil them.
I cut some willow recently as I need the bark and the wood
And as usual I stripped the bark carefully from the branch. Now in the past when I've done this there is often a red tinge taken by the wood surface as it dries but this time just overnight the change was remarkable
And here's a close up of where I scored the bark to take it from the branch
A lovely colour if only it stained the wood that colour permanently.
