With the trends in gardening veering towards more traditional plants, we will surely be seeing a return in popularity of the foxglove (Digitalis), an imposing perennial or biennial, producing tall spires of funnel-shaped flowers in different shades in early summer.

Good varieties include D. purpurea, which grows to 6ft (2m) and is great towards the back of an informal border.

For a later bloom go for D. x mertonensis, which grows to around 3ft (90cm), producing crushed strawberry-coloured summer flowers above attractive veiny leaves. Foxgloves tolerate most soils, preferably in partial shade and look as good in woodland borders as they do in cottage gardens.
