Potentilla verna is something Prof. Dostal (Charles University in Prague) used as a field test of the students' hand lenses. If you would see stellar hairs at the underside of the leaves, you had a good lens and it was Potentilla verna. Adolf Ceska

I looked at Flora North America, primarily because it is (fairly) recent and rigorous and P. verna is listed. The link below is to Potentilla verna, and does note the synonym P. neumanniana as "incorrectly applied." http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250100376 But if you look at the Potentilla genus page, it goes on for many dense paragraphs with all of the splitting and re-assigning and recombining and potential hybrids. In this situation, I tend to mistrust the taxonomy of cultivars. Clearly, from Google images, orange based petals are out there as both P. verna and P. grandiflora, correctly or not (but more often for grandiflora).

Sorry, not sure of its relationship to grandiflora and never heard it mentioned among knowledgable plant friends. Let the lumpers and splitters fight it out whilst it thrives and blooms unaware of such issues. ---------------------------------------------------------------------------- --------------------------------------------------- ... are offering /Potentilla verna/. When I look up that name on "The Plant List," it says it is a synonym for /Potentilla grandiflora/. One horticulturist suggests the one called /P. verna/ 'Nana' is /P. neumanniana/. It is a spreading plant with small yellow flowers. The other is called /P. verna/ 'Orange Flame.' This one is mound forming and has larger flowers with an orange spot at he base of the petals. Is this one really /P. grandiflora/? --Henry Fieldseth _______________________________________________ Alpine-l mailing list [email protected] http://mailman.science.uu.nl/mailman/listinfo/alpine-l _______________________________________________ Alpine-l mailing list [email protected] http://mailman.science.uu.nl/mailman/listinfo/alpine-l
