Joseph has said wispy varieties, but there many hundreds of varieties that have wispy droopy leaves , so Joseph, I don't consider wispy ones to stand out. But Black Bear, if you haven't grown a wispy one, most are hearts, then please do so.
PErhaps this link might help;

Some pictures are missing in the above link but that only happened when Houzz recently bought out Garden Web. But certain variety names are given as examples in each category.
Then there's Lutescent, nee Honor Bright and while Tania says the initial foliage is yellow it turns to green, but most of us who have grown it have found that that sickly looking foliage persists.

To date I've grown about 4,000 plus different varieties and I think I've seen almost all the wierd ones, whoops I just remembered another one that stands out, I'll go fetch it now

I can't think of any variety I ever grew that I did so b'c it was so different it stood out, other than the one I just linked to, Stick/
There are also variations of angora ones, rugose ones, RL ones and PL ones and variegated ones as well, but IMO nothing that would make the variations stand out as single varieties.
And I know I'm not remembering a few other varieties that have persistent yellow foliage, so perhaps some can speak to those.
How many different varieties have you grown to date, and I ask b'c I think you are perhaps the first person I know of who wants to actually seek out what some refer to as novelty ones as to foliage.
