Bleeding Heart Flowers: A Complete Guide to Growing and Care

Introduction to Bleeding Heart Flowers

Bleeding heart plants (Lamprocapnos spectabilis, formerly known as Dicentra spectabilis) are enchanting shade-loving perennials that have captivated gardeners for generations. Known for their distinctive heart-shaped flowers that dangle elegantly from arching stems, these low-maintenance plants bring a touch of romance and whimsy to garden spaces that might otherwise be difficult to beautify.

These charming perennials emerge in early spring and grow quickly, producing their iconic blooms in shades of pink, red, or white from late spring to early summer. The unique pendant flowers with their protruding inner petals give the appearance of a heart with a droplet beneath—hence the evocative common name.

Bleeding hearts are not just beautiful but also reliable performers in the garden, dying back after flowering but returning faithfully each year. Their ability to thrive in shady conditions makes them invaluable additions to woodland gardens, shaded borders, or any spot where other flowering plants might struggle.

Varieties and Types of Bleeding Hearts

While the classic common bleeding heart (Lamprocapnos spectabilis) remains the most recognized, there are several varieties and related species that offer gardeners different options for incorporating these plants into their landscapes:

Common Bleeding Heart (Lamprocapnos spectabilis)

The traditional bleeding heart features pink outer petals with white inner petals, creating the classic ‘bleeding heart’ appearance. These plants typically grow 2-3 feet tall and wide, making quite a statement in the garden. After flowering, they enter dormancy during the summer months.

Alba Bleeding Heart

The ‘Alba’ variety offers pure white flowers that create an elegant, ghostly presence in shaded areas. This cultivar tends to prefer more shade than its pink counterparts, making it perfect for deeply shaded spots in the garden. The white blooms stand out beautifully against the bright green foliage.

Gold Heart Bleeding Heart

This striking cultivar features the same pink heart-shaped flowers as the common type, but its foliage emerges in a bright gold color that adds another dimension of interest to the garden. The contrast between the golden leaves and pink flowers makes this variety particularly eye-catching.

Fringed Bleeding Heart (Dicentra eximia)

Unlike the common bleeding heart, this native North American species has finely dissected, fernlike foliage and smaller, but more numerous flowers. It’s more heat-tolerant and will continue to bloom sporadically throughout the summer, rather than dying back completely.

Where to Plant Bleeding Hearts

Bleeding heart plants have specific preferences when it comes to their growing location. Providing them with the right environment ensures abundant blooming and healthy growth year after year.

Light Requirements

In warmer southern zones, bleeding heart plants should be planted in a shady, cool location. The dappled light beneath deciduous trees often provides ideal conditions. Further north, they can tolerate more sun exposure, even thriving in full sun locations as long as the soil remains consistently moist.

White flowering varieties generally prefer more shade regardless of geographic location, while pink types can handle a bit more sunlight in northern areas. Morning sun with afternoon shade often provides an ideal balance in most climates.

Soil Conditions

Bleeding hearts perform best in well-draining, rich soil. They thrive in humus-rich, moist conditions with plenty of organic matter. A slightly acidic to neutral soil pH is ideal for these woodland natives.

Before planting, it’s advisable to loosen the soil to about a foot deep and incorporate plenty of organic matter such as compost or well-rotted leaf mold. This mimics their natural woodland habitat and gives them the best foundation for healthy growth.

Drainage Requirements

While bleeding hearts appreciate consistent moisture, they will not tolerate soggy soil or standing water. If you notice puddles of water 5–6 hours after a hard rain, you should either choose a different planting location or amend the soil with organic material to improve drainage and raise the level by 2–3 inches.

Good drainage is particularly important during winter months when excess moisture around the roots can lead to rot in dormant plants.

How to Plant Bleeding Hearts

When to Plant

The ideal time to plant bleeding hearts is in early spring after the danger of frost has passed and while the plants are still dormant. This gives them time to establish strong roots before the growing season begins. Dormant bare-root plants are particularly easy to handle and tend to establish quickly in the garden.

Planting in the Landscape

When planting bleeding hearts in your garden beds, dig holes approximately 2 to 2.5 feet apart to accommodate their mature size. Position the plants with their knobby roots (tubers) pointing downward and the growing points or “eyes” about an inch below soil level.

After positioning the plant, backfill with soil, gently firming around the roots, and water thoroughly to settle the soil and eliminate air pockets. Apply a layer of organic mulch around the plants, keeping it a few inches away from the stems to prevent rot.

Container Planting

Bleeding hearts also do remarkably well as container plants. Choose a large container that’s at least 12 inches in diameter with adequate drainage holes. Unglazed clay pots are ideal as they allow excess moisture to evaporate through their walls.

Use a high-quality, well-draining potting mix enriched with compost. Plant the bleeding hearts with their growing points about an inch below soil level, spacing them approximately 18 inches apart if planting multiple specimens in a larger container.

Caring for Bleeding Hearts

Watering

Consistent moisture is essential for bleeding hearts, especially through the growing and flowering period. Water deeply whenever the top inch of soil feels dry to the touch. During hot summer months, more frequent watering may be necessary to keep the soil moist but never soggy.

Once the plants enter dormancy after flowering, watering can be reduced. Container plants will require more frequent watering than those planted in the ground, particularly during hot weather.

Fertilizing

Annual feeding is recommended for optimal bleeding heart care. When foliage emerges in spring, work a time-release plant food into the soil around the plant. Alternatively, you can incorporate additional compost around the base of the plant.

This early-season feeding helps support flower production and contributes to the development of a healthy root system. Avoid high-nitrogen fertilizers that may promote lush foliage at the expense of flowers.

Mulching

Apply a generous layer of organic mulch around bleeding heart plants to help maintain soil moisture and keep roots cool throughout the growing season. This is especially important in warmer regions where heat can stress these woodland natives.

Materials such as shredded leaves, pine straw, or composted bark work well as mulch for bleeding hearts, mimicking the natural forest floor environment they prefer.

Seasonal Care and Maintenance

Spring Care

In early spring, clear away any winter mulch to allow new shoots to emerge easily. Apply a balanced, slow-release fertilizer or compost around the plants as new growth appears. This is also the ideal time to divide overgrown plants if needed.

Summer Care

After flowering, common bleeding hearts naturally die back and enter dormancy during the summer months. When foliage begins to yellow, it can be cut back to ground level. Ensure the area remains mulched to protect the dormant roots from excessive heat.

Consider planting companions such as hostas, ferns, or astilbes nearby to fill the space left when bleeding hearts go dormant. These plants will emerge as the bleeding hearts fade, maintaining visual interest in your garden.

Fall and Winter Care

In fall, a fresh layer of mulch can be applied to protect the dormant roots through winter. In colder regions, a thicker layer of mulch after the ground freezes will help prevent frost heaving.

Container-grown bleeding hearts in cold climates may need extra protection during winter. Consider moving pots to a protected location such as an unheated garage or burying the container in the ground up to its rim.

Propagation Methods

Division

The easiest way to propagate bleeding hearts is by division in early spring or fall. Carefully dig up the entire plant, preserving as much of the root system as possible. Using a sharp, clean knife, cut the root ball into sections, ensuring each division has at least one eye or growing point. Replant the divisions at the same depth as the original plant.

Growing from Seed

While more challenging, bleeding hearts can be grown from seed. To start seeds indoors, place them in a pot with soil, put the pot in a plastic bag, and place it in the freezer for six to eight weeks. This cold stratification mimics natural winter conditions. After this period, gradually reintroduce the pot to light and warmer temperatures. The change in conditions will trigger germination.

Bleeding hearts also self-seed in the garden, though not aggressively. The tiny seedlings that emerge can be carefully dug up and transplanted to new locations.

Common Problems and Solutions

Pests

Bleeding hearts are relatively pest-resistant, but they can occasionally be troubled by aphids, slugs, or snails. Regular inspection of plants, particularly the undersides of leaves, can help catch infestations early. Organic methods such as insecticidal soap for aphids or beer traps for slugs are usually sufficient to control these pests.

Diseases

Root rot can occur in poorly drained soils or during extremely wet seasons. Prevention through proper site selection and soil preparation is the best approach. Powdery mildew may affect plants in conditions of high humidity with poor air circulation. Ensuring adequate spacing between plants and avoiding overhead watering can help prevent fungal issues.

Landscape Uses for Bleeding Hearts

Bleeding hearts make excellent additions to woodland gardens, shade borders, or as specimen plants in partially shaded areas. Their unique flowers and elegant form create a focal point during their blooming season. Consider these landscape applications:

• Pair with spring-flowering bulbs like tulips and daffodils for a layered spring display
• Combine with ferns, hostas, and astilbes for a dynamic shade garden
• Plant near the base of deciduous trees where they’ll receive sun in spring and shade as the tree leafs out
• Use in container arrangements on shaded porches or patios
• Incorporate into rain gardens in areas that don’t remain waterlogged

Frequently Asked Questions (FAQs)

Q: Why did my bleeding heart plant disappear in summer?

A: This is normal behavior for common bleeding heart plants. They naturally die back and go dormant after flowering in early summer, especially in warmer climates. The plants are not dead but resting until the following spring. Consider planting companions nearby to fill the gap when bleeding hearts go dormant.

Q: Are bleeding heart plants toxic?

A: Yes, all parts of bleeding heart plants contain toxic compounds and should not be ingested. They can cause skin irritation in sensitive individuals, so wearing gloves when handling them is recommended. Keep pets and children from eating any part of these plants.

Q: How long do bleeding heart plants live?

A: When grown in ideal conditions, bleeding heart plants can live for many years, often decades. They form long-lived clumps that gradually increase in size over time. Dividing plants every 3-5 years helps maintain their vigor and longevity.

Q: Can bleeding hearts grow in full shade?

A: Yes, bleeding hearts can thrive in full shade, especially in warmer climates. In fact, in southern regions, they perform better with protection from direct sun. In northern areas, they can tolerate more sunlight as long as the soil remains consistently moist.

Q: When should I divide my bleeding heart plant?

A: The best time to divide bleeding heart plants is in early spring as new growth emerges, or in early fall when temperatures cool. Avoid dividing during their active flowering period or during the heat of summer when plants may be dormant.

With their distinctive heart-shaped blooms and preference for shady spots, bleeding heart plants offer a unique solution for gardeners looking to add interest to areas where many flowering plants struggle. Their relatively low maintenance needs, coupled with their elegant appearance, make them valuable additions to gardens of all sizes and styles.
