I had a Lisa Atemoya (cherimoya/atemoya) today and it was superb. It is not from my tree but was bought from a forum member. Great fruit.
I got a few seeds, and I'd be happy to part with them for $1 per seed.
I have a seedling of AP that I posted about some time ago, great fruit. I have seeds for sale ($1 per seed) if you are interested PM me.
I still have seeds of Pond apple, Soursop, Sugar apple (red and white) for free.
If you need USPS priority shipping, looking at $11, otherwise between $3 and $5, depending on where in the continental US you are.
Happy to trade if you have seeds you wish to share.
