Has it ever held fruit. If it will fruit here .I would take it.
This tree was a three gallon last year purchased bare root along with Sheehan and Harry's trees. The plan was to attempt fruition in South Florida. Its completely dormant right now, about six feet tall and three feet wide. It may go into bloom this Spring, but this was not a fair "winter" for testing purposes. If I had room I would plant it out for testing during a real "winter" season.
I can't imagine any low-chill cherry setting fruit in no-chill South Florida--maybe Central Florida.
The two Cherry varieties mentioned are supposedly very low chill, like low chill peaches. They are fairly new and reportedly have fruited in California with little or no real "chill", so the potential is there.
