Digitalis ferruginea (rusty foxglove) is a member of the Plantaginaceae family. This perennial exhibits a columnar upright growth habit and is characterised by its semi evergreen foliage. It has a hardiness rating of hardy (very cold winter [-20 to -15ºc]) and is hardy throughout the UK and northern Europe, with many plants grown in containers becoming damaged unless given protection.
When fully mature, Digitalis ferruginea can reach an ultimate height of 1–1.5 metres and a spread of 0.1–0.5 metres. For optimal growth, it prefers a north–facing, west–facing, south–facing, or east–facing aspect and an exposed or sheltered position. It thrives best in chalk, clay, loam, or sand soil types and should be placed in full shade, full sun, or partial shade.
