Dicentra formosa (USA)

Western bleeding heart 

to me these flowers tend to be longer than their width and they tend to bunch up toward the top of the twig and leaves are more fern like.

Bleeding heart flowers that we see in spectacular photos esp with raindrops as you said Lamprocapnos spectabilis … flowers are wider then than their red body is long and they tend to be in a neat row on the twig and when not yet fully open do look like a heart.  their leaves are not so ferny looking. and native of Japan Korea, even siberia (per wiki page )

while i wrote all this. i cant really get rid of the notion that this may be a newer cultivar called Dicentra formosa “spring gold” or even “spring magic”, because there is a question if this was of spreading habit, almost like ground cover,  but  there is no way to know the cultivar without the nursery label.

There are soooo many cultivars i stopped counting after about 10.

so my diagnosis is Dicentra Formosa.
