This is a warning...
Dolichos Lab Lab, Siratro and Silver-leafed Desmodium are running
perennial tropical legumes that many PC'ers have tried out here in the
sub-tropics as ground cover for establishing food forests. Most wish
they had never planted it/them as all are incredibly vigorous vines and
unless managed almost daily with a machete will soon smother and choke
young trees to 3-4 meters high. They self-sow readily from seed and can
be very difficult to eradicate once established.
I've seen properties with dense sirrato/siratro vine 1 meter deep over
several acres which has choked out everything else. It can't be slashed,
mown or brushcut as the strong wiry stems dont cut but wrap around the
blades and choke the machines.

These three legumes are usually grown as cattle forage and maybe in open
pasture with heavy grazing they can be kept under control.

I usually recommend cow pea which being an annual doesn't get out of
control.

The white flowering lab lab we call "Poor Man's Bean", the young tender
pods taste a little like broadbean and are fine in stir fries - grow 1 or
2 vines on a trellis in zone 1 and keep an eye on it!

For cold climates how about Tree lucerne/ Tagasaste? - prefers well
drained soil, not too acid. I'm not sure what it's minimum temperature
tolerance is but it grows well in drier inland and highland areas in
Australia with heavy frosts and light snowfall.
