A deep blue, almost purple wildflower that is not as it seems: each head, rather than being a single bloom, is actually a collection of smaller ones, huddled together.

The head-shaped inflorescence is a dense erect panicle of about 1.5–3 centimetres (0.59–1.18 in) of diameter, with usually 15 to 30 flowers.

The petals are blue or violet-blue and form small tubes with an opening at the top.

[2] This species grows mainly in grasslands, meadows, pasturelands, and pine forests.

It prefers full sun exposure on calcareous soils, at an altitude of 600–2,400 metres (2,000–7,900 ft) above sea level.
