Full details

The Thompson & Morgan Digitalis Dalmatian Mix is for gardeners seeking vibrant, long-lasting color in their borders and containers. Its key benefit is providing up to six months of summer blooms with sturdy, upright flower spikes that return each year. A caveat is that while drought-tolerant once established, it prefers moist, free-draining soil and may need winter protection in very exposed locations. This hardy perennial foxglove offers a mix of exotic colors and continues its display with side shoots after the main spike fades, making it a striking addition to mixed plantings.

FAQs

How long do the Digitalis Dalmatian Mix flowers last?

The Digitalis Dalmatian Mix can provide vibrant blooms for up to six months during the summer season, with continued interest from side shoots into autumn.

Do I need to protect these plants in winter?

This is a half-hardy perennial. While it can return year after year, it benefits from a sheltered position or a little winter protection, especially in colder or more exposed regions, to ensure its survival and robust regrowth.

What kind of soil is best for foxgloves?

Foxgloves prefer fertile, moist soil that is also free-draining. They can tolerate most soil types but will not perform well in excessively dry or waterlogged conditions.

Can I grow these in containers?

Yes, the Digitalis Dalmatian Mix is ideal for growing in patio containers as well as garden borders. Ensure the container has adequate drainage holes.

When should I plant them outdoors?

Once plants are well-grown and all risk of frost has passed, acclimatize them to outdoor conditions over 7 to 10 days before planting them in their final location.

Why are my foxglove leaves turning yellow?

Yellowing leaves can often be a sign of overwatering or poor drainage. Ensure the soil drains well and avoid keeping the soil constantly saturated. In very hot conditions, it might also indicate a lack of moisture.

Will these plants come back every year?

Yes, the Digitalis Dalmatian Mix is a hardy perennial, meaning it is designed to survive through winter and regrow in the following spring and summer.

Troubleshooting

Plants not flowering

Ensure the plants are receiving adequate sunlight (at least partial shade) and consistent moisture, especially during dry periods. Check that they are not overcrowded and have sufficient nutrients.

Yellowing leaves

This can indicate overwatering or poor soil drainage. Ensure the soil is free-draining and allow the soil to dry slightly between waterings. If in a very sunny spot, ensure adequate moisture.

Leggy growth with few flowers

Plants may be receiving too much shade or not enough nutrients. Consider moving to a sunnier position (if suitable) or applying a balanced liquid fertilizer during the growing season.

Pest infestations (e.g., aphids)

Inspect plants regularly. Aphids can often be washed off with a strong jet of water or treated with insecticidal soap. Encourage natural predators like ladybugs.

Setup, Compatibility & Care

Setup:

  1. Potting Up: If received in autumn or early spring, pot up the plants into larger containers using a good quality potting compost. Grow them on in a cool, bright, frost-free environment.
  2. Acclimatization: Before planting outdoors, acclimatize the plants to outdoor conditions over 7 to 10 days. Gradually expose them to increasing periods of outside air and sunlight.
  3. Planting Outdoors: Once all risk of frost has passed and plants are well-grown, plant them in their final positions in borders or containers.

Compatibility:

  • Sunlight: Thrives in full sun, semi-shade, or dappled shade.
  • Soil: Prefers fertile, moist, but free-draining soil. Tolerates most soil types except those that are excessively dry or waterlogged.
  • Companion Planting: Pairs well with lower-growing perennials, ornamental grasses, and shrubs in mixed borders. Suitable for mixed containers.

Care:

  • Watering: Water regularly until plants are fully established. While drought-tolerant once mature, consistent moisture will promote better flowering.
  • Feeding: Generally, foxgloves do not require heavy feeding if planted in fertile soil. A light application of a balanced liquid fertilizer during the growing season can be beneficial.
  • Deadheading: To prevent unwanted self-seeding and encourage a tidier appearance, deadhead spent flower spikes as blooms fade. However, leaving some spent spikes can allow for natural seed dispersal if desired.
  • Pruning: In autumn, cut back old stems to encourage the development of new side shoots for the following season or for overwintering.
