plants - yes. Fruits - no.
I planted a stone last spring. after I'd dropped it on the floor (accidently - but it cracked the casing) and soaked it for a week. It didn't do anything, so after the last frost, I bunged the pot in the garden. A few months later it sprouted. I brought it in before the frosts. It's now about 1ft high.
I'm going to plant a few more this year.
They don't fruit until they are something like 20ft tall. And I don't think they will grow that big in this country.
