Unfortunately Mandarino is not a commercially available variety in the US. You'll have to grow a persimmon tree from seed then graft Mandarino onto it. There are many others that are available from online retailers but most Asian persimmons are hardy to zone 7b and up. Only a few will live in colder zones like 7a and 6b. That said there are new interspecific hybrids that are even more hardy. Where are you located? I'll be happy to help you find a persimmon that will suit your area.
