I brought back some seeds from my Vietnam trip in Jan/Feb, finally getting around to sowing them. I have a handful left to give away if anyone within the US is interested. Annona seeds are viable for up to a year with good storage, works even better if you treat/soak them. Chrysophyllum seeds I don't have enough personal experience but according to some online info, they remain viable for months, hopefully it's more than 7.
