The use of the common name 'bluebell' for Wahlenbergia species is somewhat confusing as many distantly related genera also share this descriptive common name. The violet blue flowers are up to 2-3 cm in diameter and often appear to have a paler centre due to the light blue base of the petals combined with the purple style which ends in two white stigmas. The flowers may be erect or nodding and are carried on long slender stems. It is legally protected throughout its occurrence in the wild. Royal Bluebell is a charming plant in cultivation.
Propagation is possible from seeds, cuttings or root divisions.
It is suitable for growing in sunny or semi-shaded positions in cool regions, as a ground cover, and in shallow pots or hanging baskets. Well-drained soils are necessary and these may be enriched by applications of humus. Established plants respond to applications of soluble fertiliser. Flowering extends from October to March. The flowers are short-lived when cut but potted specimens in flower are suitable for indoor decoration in brightly lit positions.
