Oxalis recommendations?

Hi Jim and others

I always smile when I hear that someone grow "Ken Aslet", which is suppose 
to be a free flowering clone of O. melanosticta, because they all say it 
rarely flowers!

Those thich fleshy roots are also found on many South african species. And 
the following comments might or might not be applicable to american species. 
Those roots are contractile roots, forming at the base of the bulb and by 
desicating and contracting they pull the new nutritive scales produced 
within the old bulb out of the old bulb, downwards, where a new bulb is 
formed. The old nutritive scales die off with the leaves at autumn, and at 
the new season the new bulb will sprout.

These roots are eadible and very tasty, but do contain some Oxalic acid, if 
taken in too large quantities this could cause kidney stones.

'Ken Aslet' has never bloomed here.

Earlier this week I began to dig these Mexican sorts for storage indoors
during the winter. I've been meaning to post an image of the summer storage
roots these have, but these roots don't last long and in the past they have
been gone by the time I got around to trying to photograph them. This year I
got them, so I've added an image of the odd icicle-radish-like structures
which form beneath the bulb clusters of Oxalis lasiandra. These are also
seen in O. tetraphylla/deppei. The first time I saw these I assumed that
they were storage roots which would persist during dormancy. But in fact a
few days after the bulbs are dug they fall off or deliquesce. They are not
firmly attached to the bulb clusters and are easily detached in rough
digging. These bright white roots look very sapid to me: does anyone know if
they are edible? Take a look here:
