Eryngium campestre Field Eryngo RRR D N
At first glance this looks like a sea holly with funny leaves. It isn't glaucous at all and neither is it prostrate so you soon see the difference. This vulnerable rarity grows quite near the sea and not far from a Kiosk where the public happily trample anything in sight. This plant is probably only native in Kent and casual elsewhere according to Stace.
E. campestre is mainly found scattered over sites in southern England and the Channel islands. There are a very few sites in the north of England, a few in Wales, one in Ireland and none in Scotland.
