Botanical Description

As the authors of this taxon wrote in 1932, this differs from the well-known D. cantabrica in its habit (more intricately branched), shorter (5-7mm) and proportionately broader leaves and the more globose shape of the smaller (7-9mm) corollas, which are quite devoid of glandular hairs and of a much richer colour. In the wild there is a fine range of colour forms, but none have been successfully introduced. White plants are D.a. forma albiflora. It is doubtful if any pure plants of this species are still in cultivation; those bearing this name being the much hardier D. X scotica, but it is most desirable that the good colour forms from high up, notably on Mount Pico, are brought into our gardens. Those introduced hitherto have all proved too tender to last long out of doors.
