Flower ID help please

The rental we are in backs up to a graveyard. There's a trash pile there, and on the edge of the trash pile I noticed a clump of plants I don't think I have seen before. I don't recall there being anything blooming there in past years. I'm considering digging some up and seeing if they bloom in a sunnier location (they are in pretty solid shade where they are.)

Southwestern Missouri, zone 6 a/b. I don't know if they are native or something that was in a pot on a grave that got thrown out and is spreading.  No blooms as of last of April.

the whole clump, about 4 feet across

I'm curious what they are. Naked Ladies might be a good guess, they are all over this area, but I'd think I'd have noticed them blooming. The shade might be a problem...

Suggestions?

It also reminds me of those orange "ditch lilies" I used to see roadside in the southeast that bloomed around June (in Georgia). Naked ladies is as good a guess as ditch lilies without a bloom though.

Lots of the native Dayliliies (the orange ditch lilies) around here.  I think they make a more ball shaped clump than these, might be wrong, I'm tired and can't think tonight. They are a good guess!

Looks like yellow daylilies.

I looked up native daylilies and naked ladies. 50/50 on them. Could be either one.
hmm...
Might kidnap some. :D
