How to grow
Cultivation
Grow in moist but well-drained humus-rich soil in light dappled shade, for example in a mixed bed or an open woodland garden, or in full sun, and add organic mulch; native foxgloves are usually found in the wild on acidic soils, but they can also grow on neutral soils, and tolerate slightly alkaline soils. See foxglove cultivation for further advice
Propagation
Propagate by seed, sown in spring; it will self-seed, but may not come true unless plants have been grown in isolation
Suggested planting locations and garden types
- City and courtyard gardens
- Cottage and informal garden
- Coastal
- Wildlife gardens
- Flower borders and beds
Pruning
No pruning required, but deadheading, cutting down the dead flowering stems, may encourage growth the following year
Pests
May be susceptible to aphids and leaf and bud eelworm
Diseases
May be susceptible to powdery mildews, downy mildews and leaf spot
