Bleeding heart plants typically bloom for about 4 to 6 weeks in late spring to early summer, although some varieties can bloom over a longer season extending from spring to fall
. The common bleeding heart (Lamprocapnos spectabilis) usually flowers in mid- to-late spring, with each stem bearing multiple heart-shaped flowers from April to June
. The blooming period can last several weeks, often coinciding with cooler temperatures in spring. As summer temperatures rise, the plant usually goes dormant, and the foliage dies back, ending the blooming period
. However, in cooler climates or under optimal conditions, bleeding hearts may bloom longer or even produce a second round of blooms if deadheaded and fertilized after the first bloom
. In summary, bleeding hearts bloom primarily in spring for about 4 to 6 weeks, with some varieties and conditions allowing for a longer blooming season extending into early summer or beyond
