Pacific Bleeding Heart

Dicentra formosa

Papaveraceae

• Washington Native
• Shade-Part Shade
• Size: 10"-20" tall x 18"-24" wide
• Drought Tolerant: Moderate — tolerates dry shade once established; prefers consistent moisture
• Evergreen: No
• Flowers Color: Rose-pink to soft purple-pink (March–June - may rebloom if deadheaded)
• Wildlife Value: nectar-rich flowers attract hummingbirds, bumblebees, native bees, syrphid flies, and butterflies; larval host for the Clodius Parnassian butterfly (Parnassius clodius)

Pacific Bleeding Heart is a lush, rhizomatous perennial of moist coastal forests, streambanks, and shaded ravines from the Pacific Coast to mid elevations in the Cascades. It thrives in the cool, humus-rich, consistently moist soils of western Washington woodland gardens.  It performs surprisingly well in eastern Washington when given adequate shade and moisture, particularly in the earlier and cooler part of the growing season. Plant it in organically rich, well-drained soil beneath deciduous trees or in a shaded woodland bed. In Spokane's hotter, drier climate, supplemental irrigation during summer is beneficial, though established plants often go dormant in midsummer heat and re-emerge in fall rains.

This perennial is prized for its exceptionally delicate, finely divided blue-green foliage that forms attractive low mounds reminiscent of a compact fern. From late winter or early spring, leafless flowering stems rise above the foliage bearing drooping clusters of heart-shaped pink to rosy-purple flowers — the distinctive inflated, pendant blossoms that give the plant its evocative common name. Each cluster may hold 4–20 flowers. Blooming begins as early as March and continues through June; regular deadheading can encourage extended flowering well into summer. The blue-green foliage remains ornamental even when the plant is not in bloom and functions effectively as a groundcover in shaded garden areas.

Pacific Bleeding Heart holds ethnobotanical significance for various Pacific Northwest peoples. Several tribes used root preparations medicinally — as a wash for skin conditions and in small doses for rheumatism — though all parts of the plant contain isoquinoline alkaloids and are considered toxic in quantity. Caution is warranted around children and pets. Wildlife value is considerable: the pendant flowers are perfectly shaped for hummingbird pollination, and the plant is a documented larval food source for the Clodius Parnassian butterfly, one of the Pacific Northwest's most distinctive alpine and woodland butterflies. Bumble bees are frequent visitors, sometimes robbing nectar from the base of the flower.

In the Spokane region garden, Pacific Bleeding Heart is best deployed as a groundcover or accent plant in shaded beds, beneath canopied trees, or along a north or east-facing foundation. It pairs beautifully with Western Sword Fern (Polystichum munitum), Wild Ginger (Asarum caudatum), Wild Woodland Strawberry (Fragaria vesca), and Epimedium species. In sunnier exposures it requires consistent moisture to look its best and will go dormant sooner in summer. The true species is native west of the Cascades; cultivars are non-native hybrids.
