Yellow Oxalis lawn

Yes, and I think it depends on your location. As a veteran of the invasive
species wars, we always say, when in doubt DON'T PLANT IT. Here on Vancouver
Island we have the native Oxalis oregano who pops up in my garden, filling in a
few bare spots. It is easy to control, so I leave it alone. Native plants are so
important, and it looks nice around the camass lilies and agapanthus. We do not
seem to have the Eurasian O. corniculata in our area, and it is not noted as a
concern in British Columbia's invasive species list. Probably just means it
hasn't arrive yet!

"""There is a lot about ridding a lawn of Yellow Oxalis (Oxalis corniculata).
However I think that instead of ridding it, it might be a very attractive lawn
plant with its purple green leaves and yellow flowers, also no mowing""""

Speaking as a nurseryman battling this particularly pernicious weed, I think
that would be an unwise use of Oxalis corniculata.  Further, your local State
Department of Agriculture may have it on their noxious weed list.
Unfortunately, this particular plant spreads with incredible speed and your
neighbors may not appreciate it either.  Should you decide to eliminate this
oxalis in such large quantities, you would have great difficulties over a number
of years in doing so.  There are a number of books available now on how to have
a grass-free lawn that suggest a wide variety of far less invasive plants.  I do
hope you are not serious....
