Chocoana hasn't sprouted for me, it's been about 2 months. I'm growing these among others, all are 6-18 months:
Annona sp. Annona sp Gigante da Floresta Amazônica
Annona aff. coriaceae "Maranhão Ultra Orange"
Annona aff. coriaceae "Gigante de Maranhao"
Annona sp Diminuta (This may just be Annona deminuta?)
Annona aff muricata Sweet Columbia
Annona Nítida Pera
Both the aff coriaceae grow better than regular coriacea and sp. Gigante de Maranhao grows very very well. As well as A. reticulata, with no winter leaf loss/necrosis yet, might be evergreen. A. sp. diminuta and nitida also growing decent, the rest are either slow, cold sensitive, chlorosis susceptible, but hanging in there. I can get some pictures if anyone is interested.
