Botanic information
Leaf: The dark green leaves vary from oblong to lanceolate and are deeply lobed and are arranged in a basal rosette.

Flower: The small funnelform flowers may be pink, white or blue. They have a pale violet-blue calyx that is pubescent and is persistent after the flowers have finished. They are arranged in a panicle on a winged stem and appear during summer.

Fruit: The small nut is retained inside the persistent calyx. The small seed is not commonly seen and the plant is normally reproduced vegetatively.
