Which genus includes the species with the common name Bleeding Heart?

The genus that includes the species with the common name Bleeding Heart is Dicentra. This genus is well-known for its unique and attractive heart-shaped flowers that often have a pink or white appearance, resembling a bleeding heart, which is how the common name is derived. The most recognized species within this genus is Dicentra spectabilis, or the old-fashioned Bleeding Heart, celebrated for its beautiful arching stems and dangling flowers, making it a popular choice in gardens.

In contrast, the other genera listed do not encompass the Bleeding Heart species. Dianthus, commonly known as carnations or pinks, is recognized for its fragrant and often ruffled flowers but lacks the characteristic heart shape. Echinacea, known as coneflower, features daisy-like flowers and is used primarily for its medicinal properties and wildlife attraction. Coreopsis, or tickseed, is celebrated for its bright yellow or orange flowers and does not contain any species referred to as Bleeding Heart. Understanding these distinctions highlights why Dicentra is the correct answer, as it is the only genus associated with that particular common name.
