Serratula tinctoria, commonly known as dyer’s plumeless saw-wort, is a spineless, hairless perennial herb native to a variety of habitats across Europe, including grasslands, mires, heathlands, and open woodlands. It is widespread throughout much of England and Wales but is considered rare in Scotland. This plant typically grows between 8 to 31 inches tall and features long, hairless leaves with finely bristle-toothed edges. From July to September, it produces reddish-purple, thistle-like flowerheads that are moderately showy and attract pollinators. The species is known for its historical use in producing a yellow dye from its leaves.

Dyer’s plumeless saw-wort is valued for its low maintenance and ability to thrive in semi-natural vegetation with low soil fertility. It is suitable for wildflower meadows and naturalistic plantings, contributing to biodiversity. It prefers full sun to part shade and tolerates a range of soil types, provided they are well-drained. While not commonly used in formal garden settings, it can be an interesting addition to wildlife gardens. The plant has faced decline due to habitat loss from drainage, ploughing, and lack of management, highlighting the importance of conservation efforts in its native range.CC BY-SA 4.0
