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.

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.
