Read detailed description :

Very floriferous between May and early July, it often blooms again in late summer-autumn. Its numerous clumps of large, pure white flowers, slightly washed with pink on the edges of the corolla, produce a bright appearance. The flowers are campanulate (with a trumpet shape) and have long tubes of about 3.5 to 3.8 cm in length. Long flowering due to the lack of fruit production that could cause tiredness. Its fresh green foliage is lighter on the underside. Small, upright, well compact and dense shrub. Seedling of the variety 'Bristol Ruby'. Synonym: 'Bristol Snowflake'.
