Plant bleeding hearts in early spring, as soon as the soil can be worked, or in early fall while it is still mild (UVM, Almanac). Set bare-root plants about 1 inch below the surface and space them about 24 inches apart (Almanac). Pick part shade, ideally morning sun and afternoon shade, in rich soil that stays moist but drains well (Wisconsin, NC State). Expect the plant to go dormant in summer after it blooms (UVM). Hardy in about zones 3 to 9 (UVM, NC State).
Old-fashioned bleeding heart (Lamprocapnos spectabilis, formerly Dicentra spectabilis) is a spring perennial with arching stems of dangling pink-and-white, heart-shaped flowers (Wisconsin). It grows 2 to 3 feet tall and wide (NC State, UVM) and blooms for 4 to 6 weeks in spring (UVM). It is native to Siberia, Japan, northern China and Korea (NC State); Wisconsin says it first reached England in 1810 and became established after a second introduction in 1846. Native North American relatives include fringed bleeding heart (Dicentra eximia) and western bleeding heart (D. formosa), which bloom longer and keep their leaves through the season (Wisconsin, NC State).
When to plant bleeding hearts
| Timing | What the sources say |
|---|---|
| Early spring | As soon as the soil can be worked (UVM). The Almanac plants after the threat of frost has passed. Transplant existing plants as the first leaves poke through (Almanac) |
| Fall | UVM and the Almanac also plant in early fall while temperatures are mild, so roots settle before the ground freezes |
| Summer | Not a planting season: the plant yellows and goes dormant after it blooms, by midsummer in warm areas (UVM, NC State, Wisconsin) |
| Dividing clumps | Rarely needed; the plant resents being moved (Almanac). Divide in late fall or very early spring (Wisconsin), in fall or spring (NC State), or once dormant (UVM). Iowa State notes division is difficult |
Our planting calendar shows your frost dates. Spring planting gets you flowers sooner, while fall planting lets roots settle in cool soil; either way, UVM suggests marking the spot so you don't dig into the dormant roots later. Bleeding hearts flower along with daffodils (Wisconsin), so it makes sense to plan them with your spring bulbs (GardenPal suggestion).
How deep and far apart to plant bleeding hearts
| Bleeding heart plants | |
|---|---|
| Depth | Loosen the soil about 1 ft deep, mix in organic matter and set the roots about 1 in below the surface (Almanac). Plant potted plants at the depth they grew in the pot (GardenPal note) |
| Spacing | About 24 in apart (Almanac). Plants reach 2 to 3 ft wide (NC State, UVM), and Wisconsin says up to 4 ft wide |
| Light | Light or part shade, ideally morning sun and afternoon shade (Wisconsin, NC State). Full sun only in cool, moist climates (Wisconsin), and it won't flower in deep shade (Almanac) |
| Soil | Rich in organic matter, moist and well drained (Wisconsin); NC State says neutral to alkaline. It tolerates clay and sand if kept moist (Wisconsin, NC State), but rots in soggy soil (Wisconsin, UVM) |
| Mulch | A layer of mulch keeps moisture even (UVM, Almanac) and protects the roots from freezing and thawing in winter (UVM) |
Watering, feeding and summer dormancy
- Water the first season. Weekly for new plants; once established, only when rain falls short of 1 inch a week (Almanac). NC State says it dislikes dry summer soil and wet winter soil.
- Feed lightly. A thin layer of compost in spring is all it needs (Almanac); UVM says feed in early spring if needed, following the label.
- Summer dormancy is normal. After blooming, the leaves yellow and die back, sooner in hot or dry weather (Wisconsin, UVM). Cutting plants back hard after flowering may delay this (Wisconsin). Cut stems once they wither; the Almanac leaves 1 inch of stalk to protect the crown.
- Fill the gap. Plant ferns, hostas, hardy geraniums or astilbe nearby, which fill in as the bleeding heart fades, or add impatiens or begonias (Wisconsin, Almanac, NC State).
- Seedlings: plants self-seed, and seedlings bloom in 2 to 3 years if left undisturbed (Wisconsin).
Bleeding hearts in containers
Our sources focus on garden beds rather than pots. Because the plant reaches 2 to 3 feet and goes dormant in summer, a large container in a shady spot is a reasonable option, with a moisture-holding but free-draining mix. Move the pot somewhere sheltered in winter in cold zones (GardenPal reasoning, not a source recommendation).
Winter and dividing
- Hardiness: zones 3 to 9 (UVM, NC State); Wisconsin lists zones 2 to 8.
- Leave it in place. Bleeding heart does not like being moved and thrives for years without dividing (Almanac). Moving it can delay flowering by a year or more (Wisconsin).
- If you divide: Wisconsin divides in late fall or very early spring, NC State in fall or spring, and UVM once the plant is dormant. Iowa State lists it among late-summer dividers but notes the division is difficult because the roots are brittle and fleshy (Wisconsin).
Pests and problems
NC State reports no serious pests or diseases. Aphids sometimes visit, especially the flower stems, and slugs may eat the leaves (Wisconsin, NC State). The Almanac lists possible diseases in wet or crowded conditions, including powdery mildew, leaf spot and wilts, and suggests removing infected plants promptly. Root rot is the main risk in heavy, wet soil (UVM). Deer and rabbits tend to avoid bleeding hearts (UVM, Almanac).
Bleeding hearts around the vegetable garden
Bleeding heart is a shade plant for woodland edges and borders, not a sunny vegetable bed (GardenPal note). Because extension sources say it is poisonous if eaten, keep it out of beds where you grow food (GardenPal suggestion based on NC State). It does feed early pollinators: UVM says the flowers attract bees, butterflies and hummingbirds. Wisconsin pairs it with daffodils and Virginia bluebells in spring and with ferns, hostas, hardy geraniums and astilbe for summer. See when to plant hostas, when to plant astilbe and when to plant hellebores. Ferns fill in as bleeding hearts go dormant; see when to plant ferns, and for colorful foliage, when to plant coral bells.
Frequently asked questions
When is the best time to plant bleeding hearts?
Early spring as soon as the soil can be worked, or early fall while it is mild (UVM, Almanac).
How deep do you plant bleeding heart roots?
About 1 inch below the soil surface (Almanac).
How far apart should bleeding hearts be planted?
About 24 inches apart (Almanac); plants reach 2 to 3 feet wide (NC State).
Why does my bleeding heart die back in summer?
It goes dormant after flowering, sooner in hot or dry weather. It comes back the next spring (UVM, Wisconsin).
Do bleeding hearts need sun or shade?
Part shade, ideally morning sun and afternoon shade (Wisconsin, NC State).
Can you divide bleeding heart?
Yes, but it is difficult and rarely needed. Divide in late fall or very early spring (Wisconsin), or once dormant (UVM).
