Cirsium 'Mount Etna'
thistle 'Mount Etna'
A herbaceous perennial up to 60cm high with deeply cut, softly spiny green leaves and pincushion-like flowerheads in midsummer, and in flushes to late summer if dead headed, the flowers creamy white, tipped with protruding magenta-pink filaments; the flowers are good for pollinators, and if the last flowers are allowed to remain, the seed heads may provide food for finches
