Botanic information
Leaf: The dark green leaves are oblong to lanceolate with a reddish pubescent petiole and an acute apex. 

Flower: The tubulate flowers have a very pubescent green calyx, with reddish margins and the mauve-blue corolla is 2-lipped. The upper lip is dark purple and pubescent and the pale mauve lower lip is spreading with a white throat with purple spots. They appear in a spike during summer.

Fruit: The small nutlet develops inside the calyx and produces viable seed but the plant is commonly reproduced vegetatively.
