Bunch grapes are considered very difficult in Florida, though a few very complex hybrids have been bred that thrive here. My Mystery Grape "Gray Street Grape" made its first grape last year, a light red one.....I'd expected purple, thinking it was a native species grape due to its EXTREME vigor as it quickly consumed the henhouse and then the quail pen. Maybe due to it being 4 years old, or because I told it I'd dig it up if it did not set fruit this year, or because of the chilly wet El Nino winter we had, it is very heavily laden with grapes rapidly increasing in size. A customer and student yesterday suggested 'Red Flame' as he says it grows and bears very well here despite being a Bunch grape (vs. muscadine). But that grape is seedless...."Gray Street Grape" has seeds (good! now I can grow my own resveratrol!)
So I Googled about red bunch grapes that like Florida and I found just one likely candidate...'Daytona'. I'm guessing these thousands of green grapes will show color by July...once they do I will post pics plus a video or two.
In the meantime, my years old 'Triumph' muscadine grape on my south fence has just begun to bloom.....it looks to be a very "grapey" year indeed! John
