This looks more like a colorful cataphyll or bract than flower petals.

What planet was it growing on?

Hemerocallis "Chernobyl"???

Yep, looks like some form or hickory/walnut and is NOT a flower

Yes: new growth on a Carya

I believe Hemerocallis ' Chernobyl' was intended as a joke, DBarron

i.e. a mutant.

Carya laciniosa, Shellbark Hickory perhaps?

Most definitely Carya laciniosa.Very bizarre looking.Is the orange skin the remains of the seed case, or do mature plants also have them in the spring? Im not familiar with hickories, but I saw one coming up from seed as a kid and thought it also was bizarre looking.Their seedlings put on an almost unbelievable amount of growth the first year, don't they? Probably so the plant can reach more sun.The seedlings I saw must have been planted by a squirrel.It was in the middle of a privet hedge and was almost taller than the privet in first year. With the leaves not yet unfolded, it looks like something out of little shop of horrors with sharp fingers and thumbs.

The orange skin is the bud scales peeling back. It's not the seed case because it occurs on all the buds, not just the first seedling bud.

Thank you for the quick answer.
