Cold Hardy Mountain Coconut

Parajubaea torallyi

It has clusters of edible nuts, I think it could make a superior oil crop for marginal land in the southern USA and many other vast areas of the globe. It could replace palm oil and free up the rich land on which palm oil is grown while at the same time bringing largely unproductive land into production.

I love it when people tell me that there are experts paid millions per year to develop better crops and how they know what the best crops are and if it were good they would be growing it. Truth is most of the crop reaserch money in the world is spent on total B.S. imo. If a tenth of that were spent on the right sustainable crop solutions it's no doubt that the world would be a better place for it.

Unfortunately, Parajubaea torallyi is an endangered species. Existing stands are not regenerating themselves.
It would probably be nearly impossible to get seeds out of Bolivia, though establishing stands in other regions would be a possible way to get it off of the endangered list.

Looks a zone 8b-9a...

Don't worry John, it is already out of Bolivia,and one can get seeds:

or in england:

Or a plant in the US:

But....

"it grows protected from winds in a big hole and slopes with a special microclimate. Despite it being very dry with rain in only 2-4 months of the year, the ravines themselves are very humid. It is the only large plant that grows in the area. ... Many trials of transplanting near to its habitat have failed."

One can try...
I have no idea if I can get it here in zone 11 at low altitude.
I know rarepalmseeds because I browse it while I look for adequate palms for my place
(yes, I could get the famous canarian palm, but I am not interested in its sugar production, nor in its dangerous spines I already know too well!)

Those are some good links for palms. Thank you.
The Canary palm seeds are available here in the U.S....thorns sound nasty...ouch!

The seeds offered at this site http://www.rarepalmseeds.com/small.shtml are a small fruit cultivar likely not suited for food.
