Botanic information
Leaf: The large glossy dark gren ovate leaves are pubescent on both surfaces, but much denser on the underside. It can grow up to 300 mm (1ft) wide and develops a cordate base. The apex is acuminate and the petiole is long. The leaves are an attractive feature of the plant.

Flower: The pinkish-lilac tubulate flowers have 5-spreading lobes with purplish markings on the inside. They are arranged in an axillary upright panicle that appears before the leaves during spring. 

Fruit: The large ovoid beaked capsule is accompanied by the persistent calyx and has a long stalk. The fruit contains winged seeds that are dispersed by wind. The seeds are viable but the plant may be reproduced vegetatively.
