Cold tolerant Annona from south Brazil.
Rugulosa
Sylvatica
Neosericea
Neosalicifolia is better fruit

. . . there are quite some more cold hardy annonas though, like annona montana, rollinia (cold tolerant ones), marolo lisa, etc.
Cold tolerant
Rollinia, eh? Which species? Would that perhaps imply that certain
R. deliciosa strains are more cold tolerant than others? Which cultivars (named)? How cold tolerant? Mine just went thru 41ºF. plus several other days of 43-45ºF, too, and seems unfazed except for some leaves turning yellow. It's in a 7 gallon pot now and about 4; tall with the main trunk at 1-1/2" dia. It is out under the sky, getting full sun. Also sits in a saucer to provide it with ample water.
And, BTW, my Ilama is holding up well; its leaves are still green. It is next to an
A. squamosa whose leaves ar starting to turn yellow. Both are in 5 gallon pots and are 4' and 3' tall respectively.
There is also an Atemoya 'Gefener' which sits out near the Rollinia and is showing leaf yellowing but otherwise is fine.
Lastly I bought one of those
Annona sp. (Golden Sugar Apple, Pineapple Annona) from TT before I learned that it may just be a pond apple) and it also made it through 41ºF with no damage. And I also got from TT an
A. montana, currently in a 1 gallon pot and only 18" tall, which made it thru this same cold spell with no damage.
Hope that offers the OP some ideas about cold tolerance in Annonas. This cold spell was a good test for me and all of the other tropical fruit that I've gotten remained unaffected. Even a
Eugenia stipitata (Araça-boi) which is supposed to hate the cold and to stop growing at 60ºF, has kept growing and flowering, although it looked a bit wilty after 41ºF, but it has recovered and showed no damage other than a few of the flower buds browned off.
Cheers!
