Argentina anserina

Eric La Fountaine posting today. Today’s images are from annkelliott on the UBC BPotD Flickr pool. Original photos here and here. Thanks Anne.

Anne writes of the first photo, "This wildflower is also known as common silverweed, Indian sweet potato, and silverweed cinquefoil. This is a native, common, low-creeping plant that spreads with long, red runners. Makes excellent ground cover – for those who don’t like to mow lawns : ) Seen a few days ago at the Glenbow Ranch Provincial Park, north west of Calgary."

Argentina anserina is perennial in the rose family. It is found throughout the temperate Northern Hemisphere. Research in the 1990s led to a name change for this species from Potentilla anserina, but it appears the jury is still out, because this has not been accepted by several online databases (GRIN, Flora of China).

    At first glance those red stems were rather frightening. Clawlike!

    It’s all teeth, with a flower, ain’t it?

    like ‘eye’ runners from red pototoes…

    At first I thought it was buttercup runners which I have spent much of the day ripping from my flower beds

    Could this plant be classified as an invasive?

    i went to google on this one
    the ct-,has an
    ultraviolet image of the flower showing
    the pattern of the flower and how this
    pattern attacts the bees and insects
    the fricmann herbarium has fine images
    and the net shows old botanical drawings
    from the 1700s on down bon jour

    Really cool!
    I love this genus. I recently encountered a related species, A. egedii ssp. egedii at Salt Point State Park on the Pacific coast in far northern Sonoma County, California:

    So would ‘Argentina’ be a reference to the silvering of the leaves due to the fuzzy hairs? Sometimes I tend to mix up place names with descriptive attributes e.g. ‘florida’ etc.

    The split as Argentina was the result of a study by Eriksson et al. in 2003 (The phylogeny of Rosoideae (Rosaceae) based on sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA and the trnL/F region of chloroplast DNA; Int. J. Pl. Sci. 164: 197–211); a later study by the same group in 2007 (Phylogeny and classification of Rosaceae; Pl. Syst. Evol. 266: 5–43) put it back into Potentilla as it proved not to be as distinct as they first thought. That’s why GRIN don’t use the split.

    Link for ultraviolet photos is It is an amazing picture!

    Is this plant related to moss rose? It looks similar – both the runners and the flowers.

    For belated browsers, as of 8-13-2010 the link for UV photos listed by Mary does not seem to work. Yet it is still possible to reach the images via the Connecticut Botanical Society.
