This striking and robust short-lived perennial that is a hybrid between the pink flowered D. purpurea and the yellow flowered D. grandiflora. The resulting plant produces bell-shaped flowers in late spring and early summer, which are an intriguing mix of the two shades.
How to care for Digitalis × mertonensis:
Ensure that the soil is kept moist in summer. After the first flowerspikes have finished flowering, cut them back to encourage sideshoots to develop, which can go on to provide a second flush of flower. Then, when the last of these have died off, cut them all down to the ground. 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 often self-seed freely.

Sowing instructions:
Lightly press the seed onto the surface of a well-watered seed compost in mid to late spring and keep in a cold frame. When large enough to handle, pot on into individual cells and once they have developed a decent basal rosette of foliage they can be hardened off before planting out. They will usually start to flower in their second year.
