Saw-wort, also commonly referred to as serratula, is a flowering plant native to Europe and parts of Asia. This tall plant has a long stem and grows branching leaves and small, bright purple flowers.
It is often cultivated in gardens and flower beds, as the stunning flowers bloom throughout the summer. As the word ‘tinctoria’ suggests, saw-wort is a popular dye plant. Apart from also having been used as a medicinal plant for its anti-inflammatory properties, it can produce surprising bright yellow from its flowers. Nowadays, the plant is classified as being extinct in the wild in the Netherlands. Its Dutch name, zaagblad, similarly to saw-wort, signifies the saw-like look and feel of its leaves.
