I was going to upload a bleeding heart photo, only to find a mish-mash of either Dicentra or Lamprocapnos, often with the same cultivar names. Has there been a recent shift in this plant as well? What is the current correct genus, or are there in fact two separate ones. If so, how does one differentiate? Thanks. I'm specifically looking at the old standard Dicentra spectabulis.

Edited to note I misspelled Lamprocapnos in the post title - don't know how to fix.

Fixed spelling header, @zuzu can probably help with your question.

Dicentra is still the accepted name of a genus, but some earlier Dicentra species have been reclassified as Lamprocapnos, Dactylicapnos, Ichtyoselmis, and Ehrendorferia species. Dicentra spectabilis is now Lamprocapnos spectabilis. I didn't see any cultivar names listed under more than one accepted genus name. If you see duplicate entries, please let us know where they are.

You are right, I went through the list again and didn't see any duplicate cultivar names, just a lot of confusion. I really dislike when plants I know by their genus name get reclassified (mahonia, now some but not all dicentra). Grrr. Oh well. I will continue to call them dicentra and most garden folks will know what I am referring to (now incorrectly). I do the same with mahonia. Thanks.
