I think the (common name) Bleeding Heart vine you are looking for is a clerondendrum, not dicentra. Maybe that will help your search....

Here is a link that might be useful:

I think you're thinking of Dicentra scandens, or Dicentra macrocarpa (sp?) Both of these have the type of flower you describe. E-mail me and I'll send you some links to the places I've been searching for these. I recently ordered seeds for D. scandens from one place, but I've found another place that carries both...

The flowers for both dicentra scandens and dicentra macracapnos are yellow....

Yes---but the flowers os D. macrocarpa have q distinct orange tinge on the bottom edge---or so all the literature says. If you have personal experience whish says otherwise, please tell all!!!

I'd appreciate if anyone could post photos or links for D. macrocarpa. Thanks!

twrosz, I'm not familiar with macrocarpa, don't find that referenced in any of my material....

Macrocapnos here: (although I don't find climbing dicentra especially easy from seed, either dried and purchased or fresh from my own. When I bought d. scandens from Lazy S's Farm, I told them how frustrating I found the seed and they laughed, said their experience the same. They offer cutting grown plants :))

Here is a link that might be useful: Dicentra macrocapnos

I agree with Morz8, it sounds like Clerodendrum thomsoniae.
Dicentra scandens has ferny leaves. Clerodendrum aka Bleeding heart vine has large oval-ish leaves and the flowers are white with red.
