White Foxglove

Digitalis purpurea 'Alba', also known as White Foxglove, is a stunning and distinctive biennial plant with tall spires of white, bell-shaped flowers.

To ensure the health and beauty of this plant throughout the year, it's important to provide seasonal care tailored to its specific needs. This guide explains how to care for Digitalis purpurea 'Alba' throughout the seasons.

Spring

Pruning and Maintenance

Early spring is an ideal time to plant White Foxglove from seed or as young plants. Choose a well-draining site with partial shade or dappled sunlight and improve the soil with organic matter to support good drainage and fertility.

Mulching

Apply a 2 to 3-inch layer of organic mulch around the base of the plant to retain soil moisture, regulate temperature and suppress weeds. This is especially important in hot and dry summer conditions.

Watering

Keep the soil consistently moist, but not waterlogged, especially during the germination stage. Providing additional water during dry spells.

Summer

Pruning and Maintenance

Remove spent flower spikes to encourage the plant to continue blooming and maintain a neat appearance.

Feed

Encourage new growth by applying a balanced, slow-release fertilizer. Follow the manufacturer's instructions for the correct dosage.

Watering

White Foxglove requires consistent watering throughout the summer. Keep the soil evenly moist but avoid waterlogged conditions, as this can lead to root rot.

Autumn

Pruning and Maintenance

As the blooming season comes to an end, cut back the spent flower spikes and remove any dead or yellowing foliage to tidy up the plant.

Allow some seed pods to mature if you’d like to propagate your foxglove naturally. You can collect the seeds for future planting or allow them to self-sow.

Protection from frost

Frost protection may be necessary as winter approaches. Consider covering the plants with mulch or frost cloth, especially if your region experiences harsh frosts.

Winter

Pest and disease prevention
