Some Thistles Purpling Into Violet: Hazelbank Park

'The common thistle is known to botanists as onopordum acanthium and to everyone else as the Scotch thistle or Scottish thistle. A relative of the sunflower family, the Scottish thistle achieved fame and standing as the national emblem of Scotland. More than 200 types of thistles exist, many viewed less gloriously than the common thistle in Scotland.'
