Carline Thistle
Carlina vulgaris
A vegetable hygrometer
The carline thistle can either be a biannual or a perennial that overwinters as a rosette and dies after flowering. The slightly velvety, reddish stem reaches up to 45 cm in height. Many carline thistles have three flower heads, but not always. Beneath these artichoke-like flower heads are two types of involucre leaves (highly conspicuous bracts). The outer leaf-like leaves are short relative to the longer inner ones. They are known for their ability to respond to moisture in the air and thus act like a hygrometer. In good weather they open but when it is damp they bend inwards towards each other to form a dome over the flower to protect it from the rain.
This rare plant is restricted to dry, chalky soils with open vegetation. Traditionally the carline thistle was used as a sexual stimulant.

Carline thistle can be used in salads or as an alternative to artichoke.
In the past this plant was used as medicine. Together with Valeriana, in a ratio of 3:5, it was prescribed as an aphrodisiac.
