I picked up 2 seedlings of Erigeron carringtonae at our chapter plant sale today, grown by Elisabeth Zander from Alplains seed. Other than the one entry in the Alplains catalog, I can find absolutely no mention of this particular species. Is this a legitimate name? Is the plant THAT unknown? Is it misnamed? Help!
Erigeron untermanii only got me a few hits, and it seems as though it is quite a rare plant, or at least one that is not grown widely at all. I'm actually somewhat pleased that I've got 2, so I have a decent chance at getting one to survive and flower next year. There seem to be no photographs available but I'll keep looking.
Erigeron untermannii (syn. E. carringtoniae) from Utah
And here is another Utah Rare Plants page showing this plant (different close-up view) under its former name of E. carringtonae:
My plant named E.carringtoniae looked like that in my crevice garden under the roof overhang, growing in pure mineral substrate.
