How to Propagate Foxglove for Continuous Blooms

by

Foxglove (Digitalis purpurea) is a stunning perennial plant known for its tall spikes of tubular flowers. It adds vertical interest and vibrant color to gardens. Propagating foxglove successfully ensures a continuous display of its beautiful blooms year after year.

Understanding Foxglove Propagation

Foxglove can be propagated through seeds or by dividing established plants. Seeds are the most common method for gardeners seeking to expand their collection, while division is suitable for rejuvenating mature plants.

Propagating Foxglove from Seeds

Growing foxglove from seed is straightforward and rewarding. It allows for the cultivation of new plants that can produce blooms in the second year. Follow these steps for successful seed propagation:

  • Collect seeds from mature foxglove plants in late summer or early fall.
  • Prepare seed trays or pots with well-draining soil.
  • Sow seeds on the soil surface and lightly press them in; do not cover them deeply.
  • Maintain moist, cool conditions with indirect sunlight.
  • Seedlings typically emerge in 2-3 weeks.
  • Transplant seedlings to the garden once they are strong enough and after the last frost date.

Dividing Foxglove Plants

Dividing mature foxglove plants helps rejuvenate them and can produce new plants for additional blooms. This method is best done in early spring or late fall.

Follow these steps for division:

  • Carefully dig around the plant to lift it from the ground.
  • Gently separate the root clump into smaller sections, each with roots and shoots.
  • Replant divisions at the same depth as before, spacing them appropriately.
  • Water thoroughly and keep the soil moist as they establish.

Ensuring Continuous Blooms

Foxglove typically blooms in the first year as a biennial or perennial, depending on the variety. To promote continuous flowering:

  • Sow new seeds annually to replace plants that have finished blooming.
  • Divide plants every 2-3 years to encourage new growth and flowering.
  • Remove spent flower spikes to direct energy toward new blooms.
  • Ensure the plants receive full sun and well-draining soil for optimal growth.

Additional Tips for Success

Foxglove prefers cooler climates and can struggle in intense heat. Mulching helps retain soil moisture and keep roots cool. Be cautious of its toxicity; keep it away from children and pets.

With proper propagation and care, foxglove can provide stunning vertical displays of flowers season after season, enriching your garden’s beauty.
