Old-fashioned bleeding heart with pale pink blooms

I have gobs of Dicentra spectabilis in my garden, along with a scattering of Dicentra eximia. They all seem happy and do quite well, so that I end up needing to weed lots of baby plants.

Most of the spectabilis have the regular bright pink and white flowers, while several have white flowers ('Alba'). Anyway, last year I found one plant flowering with pale pink flowers that had no white. Unfortunately, I think I weeded it on accident. Oops. After googling, I can't seem to find any mention of this color variety for spectabilis. Has anyone ever had one bloom with that coloration before?

Are you sure it wasn't just at the end of the flowering period so the blooms were paler in comparison?

Nope! I went through my pics from last year and found some I had take on 4/28 before I weeded. Here is the pale pink:

And here is a pic, taken the same day, of a plant with the regular pink and white.

I hope it turns up again! I'm a sucker for anything in pale pink.
