Digitalis minor is a species of flowering plant in family Plantaginaceae, which has been called dwarf Spanish foxglove. It is a biennial or short-lived perennial species of foxglove which is endemic to the Balearic Islands with large, pendulous, pink or purple flowers. Closely related to the common purple foxglove, it is best distinguished by its small fruits. It is one of the only foxgloves to grow in calciferous, alkaline soils.
Local vernacular names in the Catalan language are: didalera, didals, didals de la Mare de Déu, boca de llop and herba de Santa Maria.
Digitalis minor is endemic to the eastern Balearic Islands, where it occurs on the islands of Majorca, Menorca and Cabrera.
A gene taken from Arabidopsis thaliana was experimentally inserted into the genome of Digitalis minor, creating transgenic plants. This was done to explore if the amount of cardiac glycosides could be boosted, as (other) Digitalis species are still the main industrial sources for these medicines. The metabolic engineering experiment was a success, and expression of the new gene resulted in an increased sterol and cardenolide production in the resultant plants.
