Dicentra cucullaria ?

I have been growing this Dicentra sp. for years and never got it to flower. Last year various members of this Forum advised that I should feed, feed, and feed again. So I did and, .... success! of a kind.... 1 flower spike, ;D
I always had it as Dicentra cucullaria, but now I'm not so sure. As I really don't know anything about this Genus, can someone advise me please on its ID? TIA 8)
