Here they're known as "soursobs" and you can't kill them with an axe. Or glyphosate.

The plant you uprooted was a sprout of the corm you pulled out - the corm being the product of growth in a prior season. The corm sprouts a root-like shoot that eventually grows to the surface *and* puts down roots. New cormlets form along the whole root/stem and are usually stripped-off by uprooting - a feature which makes this oxalis invasive and difficult to eradicate. > > > Since the corms are vegetative offsets the double bloom would presumably be a trait it inherited. The invasive O. pes caprae in California does not set seed - it is spread via the cormlets. I have sifted hundreds from soils all over the Bay Area where it is a terrible invasive weed... though it is also quite gorgeous this time of year, too. > > > -|<ipp > > > > > ________________________________ > From: pbs <pbs-bounces@lists.ibiblio.org> on behalf of David Pilling <david@davidpilling.com> > Sent: Tuesday, March 28, 2017 4:29 PM > To: Pacific Bulb Society > Subject: [pbs] What's going on here (Oxalis) > > Hi, > > Jim Waddick asked me to post the following question and pictures (on the > wiki page). > > " > http://pacificbulbsociety.org/pbswiki/index.php/… > Pacific Bulb Society | Things we are talking about on the ...<http://pacificbulbsociety.org/pbswiki/index.php/…> > http://www.pacificbulbsociety.org/ > 18th February 2017 I received this unlabeled plant/these plants recently at a garden exchange.
