How to Grow Foxgloves in Washington

Foxgloves, scientifically known as Digitalis purpurea, are stunning flowering plants that add a touch of elegance to any garden. With their tall spires of tubular flowers, they come in a variety of colors, including purple, pink, white, and yellow. Growing foxgloves in Washington can be particularly rewarding due to the state’s diverse climate and rich soil. This article will guide you through the process of growing these beautiful plants, from selecting the right variety to caring for them once they are established.

Understanding the Growing Conditions

Climate Considerations

Washington’s climate varies significantly from the coastal areas to the eastern parts of the state. Most foxgloves thrive in cool, damp conditions. They prefer mild temperatures and can tolerate partial shade, making them ideal for gardens in western Washington where rainfall is abundant and summers are not excessively hot.

In eastern Washington, where summers can be hot and dry, ensure you provide adequate moisture and afternoon shade to help your foxgloves flourish. Understanding your local climate will help you determine the best time for planting.

Soil Requirements

Foxgloves prefer well-drained soil enriched with organic matter. They thrive in slightly acidic to neutral soil with a pH range of 6.0 to 7.0. Before planting, it’s beneficial to amend your garden soil with compost or well-rotted manure to improve its fertility and drainage capacity.

Choosing the Right Variety

There are several species and cultivars of foxgloves suited for different growing conditions. Some popular varieties include:

Select a variety based on your garden’s aesthetics and conditions. Consider your local wildlife as well; some species attract bees and hummingbirds while others may deter certain insects.

Planting Foxgloves

Timing Your Planting

Foxgloves can be sown directly into the garden or started indoors. If you’re starting seeds indoors, do so about 8-10 weeks before the last expected frost. In western Washington, early spring or late summer is ideal for sowing seeds directly outdoors.

If you opt for seedlings, transplant them after the danger of frost has passed.

Sowing Seeds

  1. Prepare the Soil: Loosen the soil with a garden fork or tiller and mix in compost.

  2. Sow Seeds: Scatter seeds on top of the soil surface as they require light to germinate. Lightly press them into the soil but do not cover them completely.

  3. Water Gently: Use a fine mist or watering can to moisten the soil without washing away seeds.

  4. Maintain Moisture: Keep the soil consistently moist until seeds germinate, which usually takes 14-21 days.

Transplanting Seedlings

If you started seeds indoors:

  1. Harden Off: Gradually acclimate seedlings to outdoor conditions by placing them outside for a few hours each day over a week.

  2. Transplanting: Choose a cloudy day or late afternoon to transplant seedlings into prepared garden beds. Space them 12-18 inches apart to allow for their growth.

Caring for Foxgloves

Watering

Foxgloves prefer consistent moisture but do not like waterlogged roots. Water deeply once a week during dry spells, ensuring that water penetrates the root zone without saturating the soil.

Fertilizing

Incorporate a balanced slow-release fertilizer at planting time if your soil is not rich in organic matter. After blooming, you can give them a boost with compost tea or a low-nitrogen fertilizer to encourage healthy foliage growth.

Mulching

Apply organic mulch around your foxgloves after planting to help retain moisture, suppress weeds, and maintain an even soil temperature. As the mulch decomposes, it will also enrich the soil.

Pruning and Deadheading

To encourage continuous blooming, regularly deadhead spent flowers before they set seed. In late summer or early fall, cut back foliage that has turned brown or wilted.

Dealing with Pests and Diseases

Foxgloves are generally resilient but can be susceptible to certain pests and diseases:

Propagating Foxgloves

Foxgloves can be easily propagated from seed or division:

  1. Seed Propagation: Collect seeds from mature plants after flowering when seed pods turn brown but before they burst open.

  2. Division: In early spring or fall, dig up clumps of established plants and carefully separate them into smaller sections before replanting.
