This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
- Position: full sun to partial shade
- Soil: moist, humus-rich soil
- Rate of growth: average to fast-growing
- Flowering period: May to June
- Hardiness: fully hardy
Towering spikes of large, dusky, carmine-pink tubular flowers appear in May and June above conspicuously veined, dark green leaves. This foxglove is a real showstopper and looks wonderful planted in bold drifts towards the back of the border in partial shade. Although it will grow in the sun, the soil needs to remain reliably moist over summer.
- Garden care: Ensure that the soil is kept moist in summer. After flowering cut back the flowered spikes to encourage more sideshoots. Cut down to the ground after flowering. Apply a generous 5-7cm (2-3in) mulch of well-rotted organic matter around the plant in early spring. These plants are mainly biennial, although they will produce plenty of new sideshoots and self-seed freely.
