I have no idea, I have several plums close to it and it just never set.I feel kind of bad sending scion in case mine is a dud but if someone wants to waste a few years and not get anything or get some bland fruit I’ll help them out I guess.
Copy that.
Here is an article written about the weather last week that describes the high heat and humidity of this summer.
I figure that a person could pick or choose a year that it was less hot and less humid and make a point one way or the other.
But this year it appears to me that the conditions are both hot and humid…
It appears that Luisa is also grown in Australia which you stated is a different country.. I do not wish to discuss the growing in Australia.. as the current weather of Northern NZ tells me enough.
The “high” heat they quote there is 24C aka 75F. The definition of “hot” is relative to the location, the locals there call 75F “hot” because it’s as hot as it gets. 75F is a cool summer temperature by US standards and is not going to give Luisa plums any heat stress at all.
To me the jury is still out on why this plum is bland for some of us. I might have a sprout going from my ex-graft, if I find one I’ll let it grow out and see if massive thinning helps. My guess is the heat is at least a factor still.

From that link above-
North Shore recorded a temperature of 24C with 98% relative humidity. ..not merely muggy, but oppressive.
You say that you do not recommend it for a single person in a hot and humid climate… you said you would not recommend it for people in the south.
South: Includes Alabama, Arkansas, Delaware, District of Columbia, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, and West Virginia.
I think i read on here.. and various sources that Japanese plums require about the same environment as Peaches.
I am pretty sure that my favorite peaches are grown in the South.
I am also in the South.
There are growers on here with reviews of peaches and Japanese plums that are in the hot and humid climate of the South.
Luisa seems to be grown in the hot and humid parts of NZ and Australia.. even though it may not match exactly the US definition of hot.. i think humidity is fairly universal.
Hard to have a discussion on reviews of this plum from growers in the south with only a few growers in a relatively small forum with low viewership. I am not sure how a broad negative recommendation helps the cause to gain more knowledge.. but I am going to give them a try here regardless.
Sure give it a try. Since at least one person seems to be getting good results I would say it’s worth trying. I wrote that it wasn’t worth trying above before someone had posted that it was working for them in the south, and after I saw that I corrected myself above by writing
All this being said, you need to realize that 75F however humid is not going to be a heat stress climate. Facts are facts. This plum experienced nothing like southern US conditions where it originated. I still feel that heat is a major factor in whether this plum will succeed or not. But more data is needed before we will know for sure.

I have had mild and brutal summers here in my southern location. So i would say it has experienced similar summer temps that i have here.
I am not sure that this reference point of Hamilton is the deciding factor. Sure it was discovered there in the 1980s but it is also grown in various other parts of NZ, Australia etc as it seems to be sold at various Australian nurseries.
That article is about the hottest days ever recorded in the city. I don’t think that is the most relevant thing, it’s the common highs that matter not the most extreme once in a lifetime one.
You are the one that brought up Hamilton to begin with, look above in the thread.
For those of you who grow other plums in humid climates, do you have a favorite to recommend? I have a 5-year-old Methley, a 2-year-old Santa Rosa, and a 1-year-old Green Gage. None of them have fruited yet. I’m looking for 1 more plum for the orchard. Suggestions? (NW Arkansas)
I’ve never grown it but Ozark Premier was bred in Arkansas.
Thanks for the tip. I’d never even heard of this variety before.
