Bunch Grapes For Florida ?
Yes, but we have limitations.

Bunch grapes industry in Florida was spearheaded by a French immigrant named Emile DuBois in 1882.  He planted more than 150 varieties of grapes!

The industry was later wiped out many years ago by Pierce's Disease.  Pierce's Disease (PD for short) is a systemic bacterial disease spread by leaf hoppers.  Finding PD resistant varieties that weather Florida's climate has been challenging.

The main cause of poor results is the prevalence of fungal diseases during our hot, humid summers. Diseases like Powdery Mildew, Botryitis fungi, Downy Mildew and Black Rot to name the most well known.     Think cedar oil!

We will not knowingly sell
any gmo or gmo-like
plant product.

UF researchers have an ongoing grape research program in Florida.    One such researcher is investigating the use of 'cisgenic engineering', a type of gene splicing in the family of GMO processes,  to 'improve' the Thompson Seedless.

Blanc du Bois

Vitis labrusca / fox grape

Blanc du Bois is a vigorous growing, white bunch grape hybridized in 1968 by UF researchers, and named after the father of Florida's bunch grape industry, Emile DuBois.

It is highly resistant to common pests including nematodes, as well as Pierce's Disease, a bacterial infection that attacks grapes in the south. It is a hybrid cross between several Vitis vinifera varieties and the native Florida species.

Blanc du Bois is a fast growing vine with a semi-erect habit, and beautifully lobed leaves and serration. It is hardy, long-lived, and fruits well on its own roots. No grafting necessary, although some growers are grafting it a calcium tolerant, salt tolerant root stock for growing along the SE coast of the United States and the Gulf of America.

It is self-pollinating, and fruit ripens very early in the grape season: starting as early as June 30 in southern Central FL, 2wks later in North FL.

Light green berries are borne in clusters and average 45-55 berries per cluster. Clusters are medium compact, allowing for easy spray penetration where needed. (Think TX cedar oil.)

Blanc du Bois is juicy, delicious for fresh eating and also makes a spicy, white, award winning wine.

Southern Home

Vitis rotundifolia

Southern Home is a previously patented, 1979 UF release that is part bunch grape and part muscadine (Summit Red).  It has an attractive maple-shaped leaf with deep cut sinuses, and is highly disease resistant in FL.   It is self-pollinating.

Loosely clustered berries average about 12 grapes per cluster, and tend to ripen uniformly throughout the cluster. 

Although it is part muscadine, Southern Home has a thin skin, more like traditional bunch grapes.

Seed ratio is favorable at 33:1, meaning low seed count.

It is excellent for fresh eating and for jams and jellies.  Berries don't age well for wine making in previous tests.
