This looks like a Clerodendrum quadriloculare.
I agree that it appears to be a Clerodendrum, perhaps a Clerodendrum quadriloculare, also called Starburst, Starburst Clerodendrum, Shooting stars, and Firecracker bush. Although it used to be classified as a Verbena, scientific studies now place it in the Lamiaceae family, which is extremely large and includes varieties of mint and other herbs.
Starburst can be used as a small tree or shrub, depending on your preference. The maximum height is generally 10 to 15 feet (3 to 4.5 meters). Pruning is easy, and, like many shrubs, is best done in the fall, or in the spring before budding.
It thrives best in USDA Zone 9b-11 (minimum of 25°F, -4°C), which is probably where you are in Florida. It prefers acidic soil, with a pH of 7.5 or below, especially to produce full, strong leaves. Once established, though, it requires only moderate care to keep it healthy for many years.
Depending on the specific variety, leaves can be a solid color, like yours, or variegated. The tubular flower clusters attract hummingbirds and long-nosed butterflies, so keep an eye out for some pretty visitors!
This appears to be Ixora cccinea; from the Wikipedia article:
Ixora coccinea (or jungle geranium, flame of the woods, and jungle flame) is a species of flowering plant in the Rubiaceae family. It is a common flowering shrub native to Southern India and Sri Lanka. It has become one of the most popular flowering shrubs in South Florida gardens and landscapes. Its name derives from an Indian deity.
I. coccinea is a dense, multi-branched evergreen shrub, commonly 4–6 ft (1.2–2 m) in height, but capable of reaching up to 12 ft (3.6 m) high. It has a rounded form, with a spread that may exceed its height. The glossy, leathery, oblong leaves are about 4 in (10 cm) long, with entire margins, and are carried in opposite pairs or whorled on the stems. Small tubular, scarlet flowers in dense rounded clusters 2-5 in (5–13 cm) across are produced almost all year long.
