For may years known as Dicentra, one species, native to North Korea, Eastern Russia and China was moved into Lamprocapnos. Essentially treat these bleeding hearts similarly to Dicentra, grow in cool part shade, with plenty of leaf mould. From strong arching stems, dangle locket-like flowers through spring.
The unique flower structure of this and related genera restricts the range of pollinators that can access the nectar source inside; it seems to be visited especially by larger queen bumblebees. As the queens are in need of reliable food supplies when they are establishing nests, Lamprocapnos probably punches above its weight helping to ensure a supply of pollinators later in the summer.
