Not sure about seeds, but otherwise should be fine. We discussed its longevity HERE.

I've actually been looking through at that thread and every other thread on prunus sargentii in this site lol. The op said one is 40+ years old in arnold arboretum which is in MA which is zone 6a and its probably colder up there than here so it'll do better over there. So I guess my question is, does it sound reasonable to dismiss this cherry because I think the worldwide temps are increasing and this cherry will eventually succumb to fungus diseases caused by the hotter climate. And I hope that this tree could outlive me, being able to live 70+ years.

Have you been to Branch Brook Park in Newark? I'd think viewing the plantings there would be quite instructive.

Each spring, more than 4,000 cherry trees produce a panoply of blossoms -celebrated annually in a festival attracting many thousands of visitors from home and abroad. In fact, the park has the largest collection of Japanese flowering trees in one location in the United States.

Fortunately for New Jersey residents, they do not have to travel to Japan or to the annual National Cherry Blossom Festival in Washington, D.C. to appreciate this brief burst of beauty. They can take a much shorter excursion to Branch Brook Park in Newark, home to the largest cherry tree collection in the U.S., and which welcomes thousands of visitors for the annual Essex County Cherry Blossom Festival in April.

Rutgers Master Gardeners Care for Historic Cherry Trees in Branch Brook Park

I've never been there or heard of it. We generally avoid Newark because it's such a slum city full of bad people and the town is so disgustingly polluted I never even imagined of any plant life there. But that's good to know. I might visit there next year. But it doesn't state anywhere that it has sargentii cherries nor its age.

cf: the RBGE multisite search engine shows it growing in various parts of the CONUS, including Piedmont North Carolina. The supposed heat sensitivity definitely shouldn't keep you from trying it in NNJ. I'm also pretty sure I once spotted them listed in a Camellia Forest catalog.

Embothrium, you are right. I will try going soon and find out and analyze the tree. But even if there was a mature sargents cherry tree there, it means it survived all these years because decades ago was colder than it is now. I know the tree will in fact thrive where I live now. But thats only if temperatures stay the same for the next 50 years. Either ways I'll check it out!

David, thanks for the list. The one called brookside gardens is only 15 minutes away from my house and only 5 minutes away from my mom's house so I guess can go and observe that tree. But wow North carolina huh. Thats a pretty warm area. I guess maybe I can grow it here then? In 50 years my area will probably be as warm as NC's current climate.

The Edinburgh search apparently isn't comprehensive because - unless I'm missing something - the Seattle arboretum didn't come up.

It isn't meant to be comprehensive! It apparently only contains accessions databases created using some kind of software called BG-BASE that is somehow licensed through the RBGE. But it's surely the most comprehensive of its kind.

"The one called brookside gardens is only 15 minutes away from my house"

Do you have a personal fighter jet or something? I thought you were in the NYC suburbs, in northern New Jersey? The Brookside Gardens they list is the one whose name most long term horticulturalists on the east coast, at least, would recognize, which is located in suburban DC! It's where noted collector of Asian plants, Barry Yinger, got his start.

Brookside gardens is actually an apartment complex located in bergenfield, NJ. Its not even a garden. I saw the cherry from the pic.

LOL, ok that explains it. Case of mistaken identity. Excuse my ham-fisted sense of humor, I cannot help myself.

Pink Flair might be a good one to try in the OP's region. Dirr (In Praise of Noble Trees) says "Truly remarkable is the zone 7 heat tolerance as Pink Flair® maintained healthy foliage into late summer at Milliken Arboretum, Spartanburg, SC".

Although the Pink Flairs I've observed appear to have the same issue that I've seen on straight Sargent cherries - suckering from the rootstock.

I've looked at pink flair too. Size wise it would be perfect but this cultivar is always grafted and I do not want a grafted tree so I cut that out of my option.

Any Japanese cherry grafted on sweet cherry can be expected to be problematic. However the industry has used other stocks also. And cutting propagation. It all depends on what method a particular grower used, who produced the retail stock being considered at the time.

Yea that's exactly why I hate graft trees. But do you know if the Sargent cherry will become true from seed?
