If you’ve ever seen a shade or woodland garden full of beautiful pink heart-shaped flowers and wanted the same blooms for your yard, you’re in luck

In Latin, Asian bleeding heart flowers, known as (Lamprocapnos spectabilis, formerly as Dicentra species), are relatively easy to grow if you follow a few essential rules.

These spectacular-looking plants blossom in late spring and early summer, with mounds of green leaves that look a bit like parsley and arching, leafless stalks bearing the “bleeding hearts” that give the plant its name. They can be grown in many places throughout the US, from zones three through nine.

The Best Asian Bleeding Heart Flower Care Tips

Most Asian bleeding heart bushes grow to about two to three feet tall, although they can be as small as one foot and as large as four. They are perennials, which means that once planted, they will return again year after year on the same spot when adequately cared for. 

They are relatively disease-free, significantly when watered correctly, and bleeding hearts are deer resistant as well. To enjoy this popular species in your garden, read on to learn ten important tips for Asian bleeding heart plant care.

1. Planting your Bleeding Heart Bush Properly

Planting bleeding hearts is essentially a matter of selecting the correct location in the yard.

In very cool areas where they can tolerate a little more sun, bleeding hearts need partial to full shade. They are ideal for those woodsy corners of the yard that might be too dark for other species.

Bleeding hearts are also like rich, humus soil. The ground should be well-drained but able to stay moist between waterings. If the soil quality is poor where you want to plant a bleeding heart, improve it first with some compost or very weak fertilizer.

Ensure the soil is loose enough to provide proper drainage; it should be loamy, with not too much sand and clay. The addition of peat moss can help you maintain the appropriate moisture balance.

Once you find the perfect spot, plant each bleeding heart approximately two feet apart to allow good root expansion and adult plant growth.

2. Give your bleeding heart plant the right amount of water

You might want to call the bleeding heart flower “Goldilocks” because it likes its moisture levels “just right.” If the soil is too dry, the plant won’t flower, or the foliage will die off early in the season. If it’s too wet, the roots can rot, causing the entire plant to die.

Ideally, you want to water your Asian bleeding heart plant several times to get a feel for how long you need to water for the moisture to penetrate to the root level and how long the ground stays moist. Once you figure out your plant’s water needs, put it on a regular watering schedule whenever there is no rain.

Early morning or late afternoon are good times to water, as the moisture won’t evaporate too quickly, nor will it pool too long and increase the risk of root rot.

3. Mulch your bleeding hearts

Mulching is a great way to protect your bleeding heart bushes and enrich the soil simultaneously. As the mulch breaks down, it adds nutrients to the soil and feeds the plants. You can mulch your bleeding hearts in both the fall and the spring with compost, leaves, or other garden debris.

4. Maintain your bleeding hearts according to natural seasonal changes

As an herbaceous perennial, the Dicentra species undergoes a series of natural transformations throughout the year. Foliage for the plant will start to appear in early to mid-spring, and the plant flowers from late spring through the early summer.

On rare occasions in cool climates, a bleeding heart may flower twice, but this species generally only blooms once, so there is no need for deadheading or removing spent blossoms.

Depending on the amount of sun the plant receives and how dry it is, the greenery and stems will start to turn yellow and brown once the flowering period has passed. At this point, you can cut the plant to the ground if it becomes unsightly. If you do nothing, the bleeding heart will usually just die back entirely by the end of autumn.

5. Create more bleeding hearts

While you can grow Asian bleeding hearts from seed or propagate them by root cuttings, the easiest way to create more plants from your existing ones is to divide them periodically, about once every three or four years. Bleeding hearts develop thick roots at the base called “rhizomes.” You can dig up a plant, split the rhizomes with a garden spade or fork, and create two or more plants from one.

The best time to do this is in the fall after the foliage is done. If you have a neighbor with different varieties of bleeding hearts (see below), you can trade split plants to try out each others’ variations.

Bleeding heart seeds

Bleeding heart seeds are the reproductive units of the bleeding heart plant, a perennial flower that produces heart-shaped blooms in shades of pink, white, or red. Bleeding heart seeds can be harvested from the plant in late summer when the seed pods turn brown and dry.

The seeds can be sown right away in a shady spot with moist, well-drained soil or stored in the freezer for several weeks and then germinated indoors before planting in spring. Bleeding heart seeds need a period of cold stratification to break their dormancy and improve their germination rate. Bleeding heart seeds can take two to three weeks to germinate and may not produce flowers for the first couple of years. However, once established, bleeding heart plants are easy to care for and will reward you with their delicate and romantic blossoms every spring.

6. Add interest with bleeding heart flower varieties

Although pink is the classic color for “King of Hearts” bleeding hearts, there is also a white bleeding heart plant called “Alba.” The two colors look lovely when planted adjacent to each other. White bleeding hearts are also a smart way to brighten up dark corners in the yard.

Another way to brighten the forested or shady parts of the garden is to use the “Golden Heart” bleeding heart flower. This variety has striking yellow-green foliage, which is a nice counterpoint to the more common “King of Hearts.”

Some other bleeding heart flower varieties are:

  • Common Bleeding Heart (Lamprocapnos spectabilis): The classic variety with pink and white heart-shaped flowers and fern-like foliage. It grows in zones 3 to 9 and prefers partial shade and moist soil.
  • Alba (Lamprocapnos spectabilis ‘Alba’): A heat-tolerant white-flowered variety that can grow in full sun. It has the same growing requirements as the common bleeding heart.
  • Gold Heart (Lamprocapnos spectabilis ‘Gold Heart’): A striking variety with yellow-green foliage and pink flowers. It adds a bright contrast to shady areas and grows in zones 3 to 9.
  • Valentine (Lamprocapnos spectabilis ‘Valentine’): A bi-colored variety with cherry-red outer petals and white inner petals. It has burgundy stems and attracts hummingbirds. It grows in zones 3 to 9 and likes partial shade and moist soil.
  • Pearl Drops (Lamprocapnos spectabilis ‘Pearl Drops’): A pale-flowered variety with creamy flowers that are tinged with pink. It blooms longer than other varieties and grows in zones 3 to 9.
  • Burning Hearts (Lamprocapnos spectabilis ‘Burning Hearts’): A deep-pink variety with white inner petals. It has blue-green foliage and can tolerate more sun than other varieties. It grows in zones 4 to 9 and attracts hummingbirds.
  • Squirrel Corn (Dicentra canadensis): A native wildflower with white flowers and yellow tips. It has a sweet fragrance and grows in zones 3 to 8. It likes moist, rich soil and partial shade.
  • Dutchman’s Breeches (Dicentra cucullaria): Another native wildflower with white flowers and yellow tips. It resembles a pair of pants hanging upside down. It grows in zones 3 to 8 and likes moist, well-drained soil and partial shade.
  • Fringed Bleeding Heart (Dicentra eximia): A pink-flowered variety that blooms from spring to fall. It has finely cut foliage and grows in zones 3 to 9. It likes well-drained soil and partial shade.

7. Pair your bleeding heart to show it off in your garden

In addition to pairing different types of bleeding hearts to accentuate them, you can select other species that will also showcase your heart-shaped flowers. Asian Bleeding hearts look splendid next to ferns and hostas, which also thrive in shady locales. Trillium and astilbe make good companions for bleeding hearts too.

Try to choose neighboring plants that will fill in the space a bit when your bleeding hearts die back later in the season. If you’re left with a gaping hole, you could also fill the space with shade-loving begonias or impatiens. If you’re worried about inadvertently damaging the roots of your bleeding hearts, you can always stick a potted shade plant in their empty space post-bloom.

8. Mark your bleeding heart spots in the garden

Because bleeding hearts can completely disappear by the end of a fall, it can be easy to accidentally dig them up when planting fall bulbs or transplanting other perennials. If you’re worried about doing this, put a marker in your garden where every bleeding heart is rooted, so you’ll remember where it is.

9. Take care with Lamprocapnos spectabilis

As beautiful as the Lamprocapnos spectabilis is, it can be deadly, and all parts of the plants are poisonous. Take care to keep kids away from bleeding hearts, and it may be best to plant this flower where your pets can’t get at it either. Keep it out of the part of your yard where your dog romps, and take care to omit it from your horse pastures.

Just touching the plant can be an irritation to humans, too, so wear long sleeves and gardening gloves when planting or transplanting bleeding hearts.

10. Try bleeding hearts in your container garden

If you don’t have a yard or ameliorate the soil in your garden isn’t possible, you can still grow bleeding hearts in containers, provided you have sufficient shade. A sheltered balcony, stoop, or terrace makes an ideal place to enjoy your bleeding hearts in pots.

While Lamprocapnos spectabilis  is the normal garden variety, Dicentra Formosa only grows to about twelve inches tall, so it makes the perfect Asian bleeding heart for a container garden.

Lamprocapnos, with its gorgeous heart flowers and delicate foliage, is a wonderful addition to many yards. Once you get the hang of how to care for bleeding hearts, you’ll be able to have many thriving plants in your yard, and you can divide and share them at will. Follow the advice above, and you too, can enjoy these perennial winning favorites.
