The pink or purple flowered 'Scotch Thistle' is with Tartan perhaps the most identifiable symbol of Scotland. Legend has it that a sleeping party of Scottish warriors were saved from ambush by an invading Norse army when one of the attackers trod on a thistle with his bare feet. His cries raised the alarm, roused Scots duly defeated the invaders and the thistle was adopted as the symbol of Scotland.
