[MAIPC] MAIPC Digest, Vol 56, Issue 4 -violets

Tue Jun 7 09:37:00 PDT 2016

Native violets are what I recommend for a replacement ground cover.  Belonging to the family Violaceae, their leaf morphology makes the individual species difficult to recognize until they reach maturity. Rather than fescue grass and other non-native grasses that take over - it does not grow more than five inches high, does not need to be mowed and produces a flower for native butterflies, pollinators.  It works well for erosion control. Here are some that I would list that are 'keepers'. Most of them,  but not all are stemless and cordate. There are several spp. that depart from that. Here is a list  to keep: Canada Violet, viola canadensis L. Johnny - jump up, native pansy, Viola cucullata (Marsh blue violet), Viola hirsutula,  Viola blanda, Viola bicolor, Viola brittoniana (rare), Viola affinis -wetland areas, coastal plain - new variation - Missouriensis. floodplains (of course - look at that new species name!), alluvial swamps, seepage, stream banks and some cove forests. Vila esculenta, more wet areas found more northerly on the Coastal Plain. If you can persuade them to keep them they produce a delicate white violet and blue violet spp.

Hi,

I have a couple of residents in Reston who have recently expressed an interest in removing invasives from their yards. Yay! One has a large violet, photos attached, and I do not know much about violets (though I have heard about non-native species around) and so need to ask your opinion on whether this is a species of concern.

The other resident has Arum italicum in her yard and would like to learn techniques for removing it. She is aware that Roundup may not be very effective and that digging out the plant may create more spread. We are also planning on doing some control at a site where we have a few patches of the plant in the open space in an RPA. Any tips would be greatly appreciated.

Thank you,
 Patricia

Subject: Violets??

Here are pictures of what may or may not be violets -- the biggest cluster --1 & 3 -- is about 11" high.  The last is what I know is a wild violet.   I can also bring you a plant if that would help a identify it.

Thanks again,
Larry
