This is a widespread variable northern (largely circumboreal) species that extends south to Va. along the higher mountains. It was reported by Huffaker (1975) from CART and by FNA 20 from Ky., but no coll. has been located. There are older records, but at least some of these appear to have been based on misidentified Pseudognaphalium obtusifolium (M). A. margaritacea is distinct in its rhizomatous habit (with deciduous lower leaves), papery white involucres and generally dioecious flowers, which appear in late summer (Cr, FNA 20); 2n = 26 (versus 28 or more in most related Inuleae). It is sometimes grown for ornamental use (W).
