Description
Digitalis ‘Illumination Raspberry’ is a foxglove for people who want the magic for longer. Instead of a brief early-summer moment, it flowers on and on—sending up elegant spires of raspberry-pink bells from early summer right through into autumn, especially if you keep it watered and lightly deadheaded.
The flowers are richly coloured and beautifully detailed up close, with a softly patterned throat that gives each bell depth and glow. It has that classic foxglove shape—tall, graceful, and full of movement—but with a more modern, garden-ready habit that sits neatly in borders without flopping or disappearing after one flush.
It’s a brilliant plant for adding height and colour to mixed borders, cottage gardens, and pollinator planting. Bees adore it, and because it keeps flowering, it becomes a steady food source through the season—one of those plants that quietly earns its place.
Caragh Garden Notebook
Planting:
Plant in spring or autumn. Space plants 40–50cm apart to allow for a fuller clump. Choose a spot with moisture-retentive, well-drained soil. Full sun is fine in Irish and UK gardens, but part shade works beautifully too—especially if the soil runs dry in summer.

Soil Preparation:
Improve the planting area with compost or well-rotted organic matter. Aim for soil that holds moisture but doesn’t sit wet. A yearly mulch helps keep roots cool and reduces summer stress.

Seasonal Care:
Water during dry spells—this is the key to keeping it flowering for months. Deadhead spent spikes to encourage fresh flowering stems. In late autumn, tidy away tired stems; the plant will often come back strongly the following season.

Pests & Problems:
Watch for slugs and snails on young growth. Good spacing helps airflow and reduces the risk of mildew. Remove any affected leaves promptly.

Design Notes:
Perfect for long-season colour in mixed borders. Gorgeous with roses, salvias, nepeta, astrantia, hardy geraniums, and ornamental grasses. The raspberry tones also sing beside deep purples, soft creams, and silvery foliage.
