Greetings,

I assume this is Oxalis pes-caprae (which has been corrupted to "compress"?)

At any rate, this oxalis produces resting tubers that look like acorns (enough that jays and other critters spread them in the landscape). 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.

18th February 2017 I received this unlabeled plant/these plants recently at a garden exchange. It looks like Albuca shawii, and it It produced a lot of new leaves ...

Here's a plant of Oxalis compress with large double flowers, but what is
going on here.? The flowers are part of a good size clump of leaves, but
then there is a near leafless stem going down almost a foot to end in a
