A brilliant blue flower often seen by the roadside and on uncultivated ground often mixed with other flowers during phase of lush spring growth.

The purple buds open to blue flowers with a pinkish hue when young, as they mature they become dark blue.

The corolla is formed of five petals fused to form a wide funnel from which the long stigma and the two longer of five stamens protrude.

All parts of the plant are hairy, particularly notable are the rather spiky bracts surrounding the flowers.
