I got a call from jeffamy at otn.net wanting to know where to obtain
seeds for Tagasaste for establishing fields of this shrub on a ranch
in Northern Montana.
If anyone has such info couild they post it here and email it to:

I have heard that it is cold hardy and that it is not. I don't
have any references for supplies of seeds though.
Here is some limited info on Tagasaste from my archives:
Dr Laurie Snook, an agricultural researcher, has written a book
about Tagasaste. Tagasaste is a hardy, leguminous shrub. In
temperate climates it can provide heavy yields of nutritious green
fodder for grazing animals.
Tagasaste fodder can be an important base for aquaculture. It
provides a high-protein feedstock for fish food from worm farms
and snail farms, and for freshwater crustacea.
The shrub is being exploited in dryland Australia for high- protein
fodder. Even when grown on poor coastal sands tagasaste (correctly
fertilised) can produce high yields of edible dry matter containing
23% to 27% crude protein and only 18% to 24% indigestible crude
Australian farmers now growing tagasaste are reporting these
* Shade and shelter for livestock during climate stress.
* Wind and water erosion control.
* Increased soil fertility through nitrogen fixation.
* Reductions in water tables causing salinity problems.
* Habitat for native birds that eat pasture and crop pests.
* Green firebreaks around homesteads and along boundary fences.
* Winter nectar for bees.
* Reduced internal parasite problems as shrub fodder is browsed
above pasture that harbours dung-borne worm eggs.
Many Australian farmers are now following this revolution as soil
salinity and soil acidity problems make browse shrubs a most
sensible way to go in improving landcare.
We bought some seeds, I think from J L Hudson, and had zero success at
germination. Either the seed was old or we didn't scarify it right. In the
latter case, we should have gotten a little germination, at least.
I'm really interested in a source of seedlings, to side step the issue and get
into production. This would be a perfect woodn N fixer here, being on the
warm margin for Robinia psuedoacacia and on the cold margin for most useful
acacias and certainly for ipil ipil.
