It isn’t capulin cherry.
It isn’t a Prunus at all.
Looks like Barbados Cherry…
Not really a prunus type of cherry.
And the real question is…can it come back to life and grow again with 90% dead and gone.
Most likely a barbados cherry. they can survive briefly down to 28F.
It can come back alive as the roots are surely alive! It’s going to take time. After the last frosts are gone, during the early summer, prune it off. Meanwhile, if there’s still danger of frosts, do not prune, as those dead limbs would still provide protection for the trunk and growth below.
Take some of those 1" think branches and bury them deep. There is a chance they could root.
Good Research, Joe. I think your pictures, together with the one from Winter Haven, Florida confirm this is what was pictured.
Probably will re-grow. But the same thing may happen again once or twice a decade, when it gets cold in central Florida. (It got to 17F just an hour north-east of Ft. Meyers a few years ago.)
Doubt they would root, dry and brittle fire wood
Probably was a barbados cherry. The cherries on that should have three seeds. Very little to actually eat and very tart. I had one but it died upon the first freeze.
