Pristine Scarlet Beardtongue thrives in well-drained soil and full sun, requiring regular watering during dry spells but allowing the soil to dry between waterings. Deadhead spent blooms to encourage continuous flowering and maintain a tidy appearance. In early spring, cut back the previous year's growth to promote vigorous new growth. Fertilize sparingly with a balanced, slow-release fertilizer to avoid excessive foliage at the expense of blooms.
