Unknown Erigeron

There's a phrase to strike fear in the hearts of an amateur botanist...almost as bad as "Unknown Arnica".
I obtained seeds of Erigeron aureus from this spring's NARGS seed exchange, was was delighted to get good germination. But the plants, which have not bloomed, have rosettes of very large, very hairy leaves, quite unlike the E. aureus that we find in the Rockies. I wonder what I've got!
Will attach photos of E. aureus from a hike this summer to Parker Ridge in Banff Nat. Park, and then the unknown plant.

sp. -
H. villosum
?
Hieracium villosum
The wee little kid is pretty cool, too.

Another case of mistaken identity for
Erigeron aureus

Thanks to both of you. I think Rick is right. But the Hieracium villosa may be a zone 4 plant, so we'll see if it survives the winter.

Linda, I'm pretty sure any
Hieracium
would be hardy on the moon or Mars...
Many are classified as noxious weeds in many areas... more to the point though, I've grown
Hieracium villosum
for a great many years here and it is completely hardy.
Wish I could send you some seeds for the real thing... unfortunately, I didn't collect any this year, but I'll check my seed stores.

Thanks for the kind offer, Lori, perhaps we'll meet up at a CRAGS meeting sometime.

That looks like the plant I get every time I try to get E. aureus seed from seed exchanges.
