Marsh Thistle - Cirsium palustre
Medium to tall plant to 1.2 metres, stems spiny-winged to the top, sometimes branched above. Leaves linear lanceolate, pinnately lobed and very spiny, mostly unstalked, hairy above. Flowerheads usually purple, 10 to 12 mm in clusters of 2 to 8. Flower bracts purple tinged, erect, weakly spiny.
Mostly easily confused with Welted Thistle but can be distinguished by its feathery seeds. Welted Thistle has seeds with down that is unbranched.
Wet habitats, woodland clearings, wet ditches and marshes.
July to September.
Common throughout Britain.
Quite common in Leicestershire and Rutland. In the 1979 Flora survey of Leicestershire it was found in 379 of the 617 tetrads.
