Genus:Lamprocapnos

Species:spectabilis

Family:Papaveraceae

This plant enters a dormant phase during the summer months in warmer climates, but you can encourage it to bloom on Valentine's Day by placing dormant rhizomes in a cool greenhouse during late winter.

Dicentra spectabilis showcases a stunning array of colors, ranging from vibrant pinks to soft whites with pink accents, as well as pure white and gentle pink hues. These flowers are guaranteed to be a striking addition to any garden. The charming, heart-shaped blooms evoke a sense of nostalgia reminiscent of the Victorian era, highlighting the beauty this plant can bring to your outdoor space. Their lively colors seem to sway gracefully in the spring breeze, adding a touch of joy to the landscape.

Belonging to the Papaveraceae family (previously classified as Fumariaceae), this plant can be identified quickly by its erect perennial herb structure, reaching heights of 2 to 3 feet, with branches and flower clusters arching gracefully at the top.

It typically flowers from late spring to early summer, featuring inner petals that extend outward, creating the appearance of "bleeding" from the outer heart-shaped petals. By mid-summer, the foliage turns yellow and falls off as the plant dries out, making regular watering essential. This plant is often used as a cut flower, a potted plant (often referred to as a "living valentine"), in shaded borders, or as a filler plant. The variety D. eximia offers a longer blooming period and has more finely dissected leaves, making it a modern alternative to this classic garden favorite.

It thrives in partial shade and requires sufficient moisture, although it can be susceptible to fungal diseases. Seeds can be sown in late summer, and plant division can be performed in either fall or spring. This species is commonly found in forests and other natural habitats, thriving in rich woodland environments.
