Botanic information
Leaf: The dark green broad-lanceolate leaves have a leathery texture with banding in silver-grey. The margin has small spines and the leaves tend to fold inwards and are arranged in a rosette that forms a vase shape.

Flower: The tiny blue tubulate flowers are surrounded by pink bracts that are stiff and pointy. The spike-like inflorescence is terminal appearing on a white woolly stem that is up to 80mm (3in) long during summer.  

Fruit: The small berry is not commonly seen and the plant is normally reproduced vegetatively.
