When do Grape Vines blossom?

Question

I have a Muscadine Ison, here in South Florida. If I'm lucky enough to get flowers, when might I expect them?

Answer 1

Early summer typically. Mine have already flowered and I'm finally getting fruit after several years of waiting. It really depends on how old the vine is. My vine was two years before it flowered the first time and and didn't produce fruit until the third year. I've heard that the fruit won't be great until the 5th year.

Answer 2

It is first Sunday of Atom
