Bleeding heart, or lamprocapnos (formerly dicentra), are elegant, shade-loving perennials grown for their pendulous spring flowers. As woodland plants, they're ideally suited to cool, shady spots in the garden with moist soil, including in containers.
(So says the Internet)

They have just come into flower in our garden, they look so beautiful.
A sunny afternoon and I am enjoying it as we have not had much sun lately.
