I can exchange maprang or yellow guanabana seeds. I have neither now but can send maprang next season, november december.
I used to be able to collect yellow guanabana at a friends place but he might have cut it down cause it’s not as productive as the green one. So can’t say for sure now.
Red grapefruit seeds i can get quite easy since have trees her, can toss in some with maprang.
Have a look at my most recent exchange post for more seeds that I have available.
Peace!
