Woolly Thistle - Cirsium eriophorum

Medium to tall stout plant that may reach 1.5 metres. Stems are unwinged, white-cottony usually branched above. Leaves pinnately lobed, with long ridged spines, white cottony beneath. Flowerheads are large, cottony-hairy, reddish purple 25 to 50 mm; usually solitary, erect, outer flower bracts recurved and spine tipped.

A very large plant.  As with all Cirsium, the pappus-hairs (the silky white hairs attached to the seed - the thistledown) are individually feathery or branched.
