Well you need to 'key' the plant out. This is Dr. Wunderlin's key for wisteria from his book the Guide to the Vascular Plants of Florida.

1. Ovaries or fruits glabrous; pedicels 5-10 (15) mm long … W. frutescens

1. Ovaries or fruits densely pubescent; pedicels 15-20 mm long

2. Flowers opening almost simultaneously; corolla 2 - 2.7 cm long ... W. sinensis

2. Flowers opening is a gradual sequence from base; 1.5 - 2 cm long ... W. floribunda

Wisteria frutescens is the native American wisteria, Wisteria sinensis is Chinese wisteria, and Wisteria floribunda is Japanese wisteria.

To check to see if it has been documented for your county you can go to the Atlas of Florida Plants.

From the photo I would guess it to be Chinese wisteria, but you should key it out to be sure.
