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.
