Folxglove & Mullien - which is which?

Foxglove
Order: Lamiales
Family: Plantaginaceae[1]
Genus: Digitalis L.

The first year of growth of the Common Foxglove produces only the stem with its long, basal leaves. During the second year of the plant's life, a long leafy stem from 50 to 255 centimeters tall grows atop the roots of healthy plants.

Digitalis thrives in acidic soils, in partial sunlight to deep shade, in a range of habitats including open woods, woodland clearings, moorland, and heath margins, sea-cliffs, rocky mountain slopes and hedge banks.[4][8] It is commonly found on sites where the ground has been disturbed, such as recently cleared woodland, or where the vegetation has been burnt.

Mullien
Order: Lamiales
Family: Scrophulariaceae
Tribe: Scrophularieae
Genus: Verbascum L.

The plants first form a dense rosette of leaves at ground level, subsequently sending up a tall flowering stem. Biennial plants form the rosette the first year and the stem the following season. The leaves are spirally arranged, often densely hairy,
