Carline thistle

Carline thistle is a natural hygrometer. During dry sunny days, the petals are spread out. If the air is humid, the petals start to curl up and if it rains, they form a dome over the heart of the flower. Carline thistle makes a very good dried plant. In fact, it is someitmes more obvious in the winter when all other growth is less prominent. The dried stems and flowers often remain upright till the next spring. Even in the winter the plant still acts as a hygrometer. Carline thistle is popular among songbirds such as linnets and goldfinches and various insects.

  • Distribution and habitat

    Carline thistle grows on sunny, dry calcium-rich, humus and moderately nutrient-poor sandy soils, especially in the dunes on slopes and in dry slacks. If the dune vegetation is too thick, the plant will disappear. Outside of the dunes, it grows in calcium-rich grasslands. Carline thistle often has three flower heads, which explains the Dutch name 'three thistle'. The plant usually blossoms in its second year, and sometimes in following years. It spends the winter as a rosette of leaves.

    Carline thistle is found from southwestern Europe up to the North Sea region and Scotland.
