I’ve learned several fun facts about saffron this week, both during and after making this graphic. Firstly, I hadn’t realised that saffron is obtained from the stigmas of one species of crocus. Secondly, I hadn’t realised that a town not too far from me, Saffron Walden, does indeed take its name from its historical production of saffron.
This new graphic
focuses on the chemistry of crocus colour, and also takes a look at the potential dangers of confusing the different plants which are nicknamed ‘autumn crocus’.
I also made a crocus pH indicator from one of the purple crocuses in our garden, worth it for the vibrant blue produced!
