Description
http://en.wikipedia.org/wiki/Cirsium_vulgareCirsium vulgare
Spear thistle is designated an "injurious weed" under the UK Weeds Act 1959,[9] and a noxious weed in Australia[8][10][11] and in nine US states.[12] Spread is only by seed, not by root fragments as in the related creeping thistle C. arvense. It is best cleared from land by hoeing and deep cutting of the taproot before seeds mature; regular cultivation also prevents its establishment.[5]
