There are about 20 species of foxglove, all of which belong to the genus Digitalis. The best known species is Digitalis purpurea, the common foxglove. Extracts from foxgloves are used to manufacture digitalis, a drug used to treat cardiac conditions.

Campion is the common name given to various flowering plants of the Lychnis and Silene genera. Campions found in Britain include the red campion (Silene dioica), the white campion (Silene latifolia) and the bladder campion (Silene vulgaris). Of these, the latter two could be described as "pale".
