Hi Miguel, all this information is valuable, thanks. Then the Jaboticaba who died was young, 4 or 5 years does not produce a very high tree or a very thick trunk.
Also, we dont know why did it died, and I guess it had no frost protection at all.
Small Myrciaria trunciflora surviving -5º C/23ºF (or less, as you can get -6ºC/21ºF there) would be great!
Jaboticaba apimentada sounds good too! maybe it resists more than -7º C/19ºF? would be great
Please take care of this bigger M. truncifolia in your GH,
will you cold acclimate it? see:
http://tropicalfruitforum.com/index.php?topic=10481.0Didnt knew MYRCIARIA DELICATULA (
http://www.colecionandofrutas.org/myrciariadelicatula.htm), it seems very tasty too, sweeter than uvaia+araza
"Marcos,
the South Brasilian / Uruguayan species will be our best bets for sure", yes, m. sabara grows in the argentinian north, my sabaras are from Paraguay.
Adam: "I have no experience with M. tenella, but I know it is one of the most cold hearty", for sure it should be! some months ago I was looking for jabos from Uruguay, and it's maybe the only one that grows there in the wild (

Your list is very very useful, thanks! maybe we should add the above mentioned species (and I think rivularis should be tougher)
