You must have seen one you liked. ;-)

Mine was 8-10 feet tall when I bought it in spring of 2001and it shows no sign of decline. Some issues with branching structure that I missed when I got it, but otherwise its doing well.

Sargent cherry lives long enough to get big (80' tall in the wild). Seattle arboretum plantings of this species date back as far as 1940, I haven't looked at tags of these there recently but probably the same individual(s) are still present (as recently as 2005 at least 17 examples were in the collections there).

Whaas,
We planted about a dozen Sargent cherries roughly 20 years ago. I haven't noticed any major concerns with pests or diseases, but they don't appear to be very compatible with their rootstock. Most of them have large swellings under the graft union. Not sure if any nurseries are growing them on their own roots, but that would probably help promote longevity.

Liable to be on sweet cherry.

I have a 10-year old Prunus sargentii. It's at least 25 feet tall, healthy and doing well. I live near coastal NJ

All, thanks for the feedback. I'll give one a shot. Blooms and fall color on one tree make it worthwhile.

I called the source and its budded to Prunus avium, but they called is Mazzard Cherry which is the sample thing I believe.

That fact its grafted to Prunus avium...would that change anyone's opinion as to its lifespan?

Look until you find one raised from seed or even a cutting. In addition to possible delayed graft incompatibility there is the possibility of the aforementioned ugly differential between the diameter of the sweet cherry stem and the stem of the Sargent cherry, as well as likely issues with emergent roots and suckers - here in western USDA 8 sweet cherry root-stocks are often a nightmare in parking strips and other turfed or paved areas.

A visual aid to the potential difference in scion/rootstock sizes - and it can get worse than this! However, I think this amount would warrant removal in your yard.

The tree in the pic is an ash IIRC

Rooting of the scion via slow burial with soil might be possible. In addition to the bulging stock becoming obscured it might have the benefit of getting the scion onto naturally oriented roots - the lopsided appearance of the stock makes it appear it is in the too common deformed condition resulting from overly long confinement to a small container.
