Thistle

Flowerheads of Creeping Thistle, Cirsium arvense, coming into bloom beside a minor road near Inverurie, Aberdeenshire.

[Known as 'Creeping' Thistle - despite its upright habit! - because it [url=http://www.plant-identification.co.uk/skye/compositae/cirsium-arvense.htm]spreads by creeping roots[/url].]
