Digitalis purpurea (Common foxglove)
D. purpurea is a biennial plant, forming a basal clump of leaves in its first year, then tall, upright spikes of purple-pink, bell-shaped flowers in its second year. If allowed to self-seed, it will replenish itself in the garden.
Plant in almost any soil or situation except very wet or very dry. An ideal site is a humus-rich soil in part shade. Seeds can be planted in situ and plants left to self-seed after flowering. Will reach a height of 1.5m and a spread of 0.5m after 1-2 years.
