Sound like you seen a mature tree there? can you take us a picture of it and link it? I only saw a seedling with two leaves once, probably no more than 3 inches, and probably priced near $100, I was just saying $50 for for cheapest tree in general, The Cherimoya you are referring to 2-3 years is around $70 - $100. Might not be over priced for you, but comparing to other nurseries they are generally
more expensive. My Cherimoya grown from seeds 2 years is bigger than offered there.
I would happily pay $100 if they had Luc's Garcinia 3 years old and like described, again please take us a picture if you can find it.
