Cirsium palustris

Visible now

Visited by 80 pollinating species

The marsh thistle, Britain’s tallest thistle, is so rich in pollen that it is known to be visited by at least 80 species of bee, butterfly and fly.

Marsh thistle’s flowers are a good example of early, simple stage of evolution – all flower heads are alike with no division between inner and outer petals.
