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

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

Hi ,we grew Oxalis pes-caprae double form in Deloraine,Tasmania and
