Foxgloves are popular in a host of planting styles from traditional cottage gardens to the contemporary perennial plantings of Piet Oudolf and the New Perennial movement.

There are 25 species and forms in the genus Digitalis, found throughout Europe, northwest Africa and central Asia in a range of habitats from woodland clearings to sub-alpine meadows. The only true biennial is Digitalis purpurea and its cultivars, although some modern purpurea foxglove hybrids are classed as short-lived perennials.

Most foxgloves, including ancient species and modern hybrids, are perennials, whose lifespan varies according to the growing conditions but is usually three to five years.

Perennial foxglove species are divided into two groups: herbaceous perennials, such as Digitalis grandiflora and Digitalis lutea, which die down during cold winters and those retaining an evergreen rosette, including Digitalis parviflora and Digitalis ferruginea.

When do foxgloves flower?

The foxglove species flower from early to midsummer but the new hybrids are sterile, so flower for a longer period – from spring to autumn and beyond during mild winters – because they do not set seed. They also tend to swap elegance for robustness, producing denser spikes of more upright flowers.

Where to plant foxgloves

The natural elegance of all the cultivated species can be used to add lightness, romance or architecture, depending on the scheme. Smaller species, such as Digitalis lutea and long-flowering modern hybrids, including Digitalis purpurea ‘Dalmation Peach’ with its subtle, pale-apricot flowers, are ideal for growing in pots in courtyard gardens.
