Mine are at least 4 weeks later.

Strangely my first fruit are also around the same time. About one month ahead of H118. It does have a long season here - extending into early October.

Thanks for the informative reply!
Our lowest that we have been in the last couple decades has been -10, but even that is getting quite rare. Usually 0 is our minimum on an annual basis, and many years only around 5. I also have many mellow microclimates, but overall I think I will stick with natives for now!
I’ve been here for 13 years. Our lowest temps were early Feb 2023, when we had -7 F one night and -5 F another. My three in-ground IKKJs nearly died – all wood <3 years old was killed. Three years later the trees have almost fully recovered.
My search of weather records indicates that Scituate RI dropped to almost -9 F then. One night at those temperatures will kill almost all Kakis and many hybrids. So IMO you should grow only (1) Americans and (2) proven cold-hardy hybrids.

And yet my Great Wall survived -7 in a protected spot, but I wonder why shoots above the wall were not burned. Great Wall is reputed to be one of the hardiest ones… what surprised me was how large and sweet they were. Maybe better than real good store boght fuyus… but I am the mother.
One good season is not a reliable test, of course. But -7 is as low as its gotten for about a decade, I think.
