The Weeping Heart Flower (Lamprocapnos spectabilis) is a herbaceous perennial plant of the family Papaveraceae, known for its elegant appearance and distinctive flower morphology. Originating from East Asia, this species has gained an important place in the ornamental plant trade worldwide, especially as a garden plant. The most striking feature of the flower is its heart-shaped and drooping flowers. For this reason, it is also popularly known as "weeping heart" or "bleeding heart". Lamprocapnos spectabilis has a multifaceted botanical, ecological, cultural and economic importance.
Taxonomy, Morphology and Systematics
Taxonomic Classification
Lamprocapnos spectabilis was classified by Carl Johann Maximowicz in the 19th century and was originally known as Dicentra spectabilis, but molecular phylogenetic analyses led to its separation into the genus Lamprocapnos. This taxonomic change revealed that the plant shows significant differences from other Dicentra species at the morphological and genetic level.
Morphological Features
Lamprocapnos spectabilis is a rhizomatous, herbaceous plant that grows 60-120 cm tall. The stems are soft and succulent. Leaves are deeply lobed, light green in color and arranged opposite each other. The leaf blade is glabrous and the margins are segmented. The flowers are drooping and heart-shaped, with a second teardrop-like structure in the center. This structure is formed by the inner appendages of the petals and gives the flower its characteristic "weeping" appearance. These flowers are usually pink-white in color, but in some cultivars they can be completely white or red. The flowering period lasts from late spring to mid-summer.

Systematic and Molecular Data
Traditionally classified in the genus Dicentra, molecular analyses (using chloroplast gene sequences such as rbcL, matK) have classified the species in a different clade. This shows that it is evolutionarily distant from morphologically similar species. There are distinct differences in this species especially in terms of floral symmetry and perianth structure.
Ecological Distribution, Habitat Characteristics and Cultivation
Natural Distribution Area
Lamprocapnos spectabilis is naturally distributed in China, Korea and Japan. It grows in moist and shady areas under forest cover. In terms of altitude, it is usually found in areas from sea level to 1000 meters. Its tolerance to moist soils and its ability to grow in partial shade allow it to live naturally under dense forest cover.
Habitat Characteristics
This species especially prefers humus-rich, well-drained but moist soils. It grows optimally in soils with acidic to neutral pH ranges. Photosynthetic efficiency increases in semi-shaded or filtered sunlight, while leaf burns and growth retardation can be seen in direct and intense sunlight.
Growing Conditions and Landscape Use
Lamprocapnos spectabilis is widely used in horticulture and landscape design for its high aesthetic value. Since it is difficult to propagate from seed, it is mostly propagated vegetatively by dividing the root rhizomes. Sufficient space must be left when planting because the plant tends to spread. In terms of maintenance, it requires low levels of labor but is sensitive to drought stress. Regular watering is therefore important.
It is often used in landscaping to enliven shaded areas. Since it starts to turn yellow before leaf fall, this effect can be disguised by using it with other herbaceous species at the end of the season. Due to the toxicity of the plant, caution is required for children and pets.

Cultural and Symbolic Meanings
Lamprocapnos spectabilis has deep meanings, especially in East Asian cultures. In Japanese culture, it symbolizes love and heartbreak, while in Korea it is a metaphorical element in traditional poetry and artworks. In Western culture, it was accepted as a symbolic plant expressing love during the Victorian period. In the Victorian "language of flowers" (floriography), this plant was used to mean "love pangs" or "secret feelings".
Conservation Status and Ecological Risks
No direct threats to natural populations of Lamprocapnos spectabilis have been reported. However, over-collection from natural areas, habitat degradation and microhabitat loss due to climate change may pose a threat at the local level. In this context, it is important to prevent commercial propagation and unauthorized collection from the wild. There is no official conservation status for this species in the IUCN (International Union for Conservation of Nature) database.
