Digitalis purpurea 'Pam's Split'
  • RHS Plants for pollinators

foxglove 'Pam's Split'

'Pam's Split' is a biennial or short-lived perennial up to 1.2m high with overwintering rosettes of grey-green leaves, and several spikes of white flowers, spotted and blotched maroon inside, the corolla split rather than fused as in most foxgloves, in early summer; wild native foxgloves are a reliably good source of nectar for bumblebees, especially long-tongued bumblebees, and some but not all garden cultivars may also be good bumblebee plants: the flower shape of 'Pam's Split' may make it less attractive to bumblebees

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, 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

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
  • Wildlife gardens
  • Coastal
  • Flower borders and beds
Pruning

No pruning required, but deadheading, cutting down dead flowering stems, will 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
