If you have a sandy well drained soil, the Lotus rootstock with be better for you. If you have a heavy soil, the American Persimmon rootstock is best. In Central and Southeast Texas, some orchards had to rip out all the Persimmons on Lotus because we have a heavy soil and they had problems with growth and root rot. Most trees that come out of CA will be on Lotus and the ones that come out of Texas will be on American.
I like the Fuyu but Jiro is pretty much the same fruit. At least, I dont notice a huge difference in taste.
