The most popular is Jacaranda mimosifolia which is called Blue Jacaranda, more often known simply as the "Jacaranda"
It grows to a height of 40 to 50 feet and grows a Spread of 50 to 60 feet.

It grows fast usually 3 to 4 feet a year (if the soil is kept moderately moist most of the year. Dry condition will slow it down and it will not do as good) It might could even grow around 5 feet a year if the soil is rich, moist, and well drained. It is adaptable to many soil conditions even poor sandy soils but will not grow in an area of poor draining swampy soil. And it doesn't like salt.
The wood of the jacaranda tends to be brittle so be sure to train it to have one central trunk and major limbs well-spaced apart for street tree and other high-use areas. Unpruned side branches that grow almost straight up can become hazardous as they can split off the trunk at the crotches (base of the branch where it meets the trunk).

Here's a picture mine at time of purchase two years ago and the other was just taken at about 22 feet tall. We live in Florida and it's been growing like crazy. No blooms yet though

Mike what are you feeding it to grow that fast? I live in Florida also and just bought one today. Looking for any tips you may have.
