One of the strange gems of the Burren, this biennial looks good whether on flower or when its heads are full of feathered seeds. It's a short, prickly, stout little thistle with amazing golden-brown-tinged-purple, rayless flowers (15-40mm) with conspicuous, spiny, sepal-like yellow bracts which spread widely apart beneath. These are on densely prickled, leafy stems and close up in wet weather. The oblong leaves are wavy with spiny lobes. This plant is also attractive when it's finished flowering as it leaves a very dry skeletal form of itself. On flower from June to September, it is not a frequently found plant, its habitat being sand-dunes, dry pastures and gravel-banks. It is a native plant belonging to the family Asteraceae.
I first identified the Carline Thistle in Ballyvaughan, Co Clare in 1978 and photographed it there in 1995.
