F lowering trees are an important component of central Florida landscapes. They provide colorful flowers during their season of bloom. Many of these trees also make nice shade specimens. Our climate here in central Florida allows for a wide range of flowering trees to be used. We can grow some of the hardier, temperate climate trees and trees from subtropical and even tropical climates. The following are some of the flowering trees that grow well in our area. For the gardener who is adventurous or who lives in a very warm and protected microclimate, there are a few tropical flowering trees that are worth the effort. The Royal Poinciana, Delonix regia, is a native of Madagascar. It is a fast growing tree reaching 30-40 feet tall with an umbrella shaped canopy. It flowers in late spring and summer. The tree is covered in orange to scarlet red flowers. This is one of the most spectacular of all flowering trees. It is very common in southern Florida. A close relative is Colville’s Glory, Colvillea racemosa. It is also native to Madagascar. It grows 30-40 feet tall. It resembles a Royal Poinciana when it is not flowering but has much less of a spreading canopy. It flowers in fall and bears racemes of orange flowers at the tips of the branches. Schizolobium parahyba, the Fern Tree, is native from southern Mexico to Brazil. It is an extremely fast growing tree, especially for the first several years. (It can grow 10-20 feet in a couple of years.) It does not branch until it is about 20-30 feet tall. It has long pinnate leaves and resembles a giant tree fern in this growth phase. It can grow 40-60 feet tall with a high canopy. It bears yellow flowers during the summer. The African Tulip Tree, Spathodea campanulata, is a native of tropical Africa. It is a fast growing tree reaching 30-40 feet tall. It bears orangish-red flowers in spring and summer. S. campanulata var. lutea bears yellow blooms. Kigelia africana, the Sausage Tree, is a real curiosity. It is native from tropical Africa to southern Africa and grows 30-50 feet tall. The dark maroon flowers appear in summer and hang from the tree on long stalks. If these flowers get pollinated, large spongy seed pods appear. These pods can be 1 to 2 feet in length and resemble sausages. For those gardeners that miss flowering trees that heralded the arrival of spring in more northern parts of the country, several of these trees can be grown in central Florida. Eastern Dogwood, Cornus florida, can be coaxed into growing in local landscapes. They grow 10-15 feet tall and bare white flowers in early spring before the leaves appear. They are not as showy bloomers as they are further north. Eastern Dogwood prefers a lightly shaded location (at least in the afternoon) and moist soil. They also need good air circulation. For central Florida, it is best to grow the cultivar ‘Weaver’s’ as it is the best heat tolerant variety. The pink forms will not grow here. Eastern Redbud, Cercis canadensis, is another spring bloomer that flowers before the leaves appear. It bears small rosy-pink flowers along the stems. It has similar requirements to Eastern Dogwood. ‘Forest Pansy’ is a variety that has burgundy colored foliage when it first emerges. It usually fades to green by mid-summer. C. racemosa ‘Avondale’, the Chinese Redbud, has performed well here at Leu Gardens. It flowers in spring like other Cercis but ours also has a light bloom in the fall. American Fringe Tree, Chionanthus virginicus, is another spring bloomer that grows well here. It can be grown in sun or shade but looks best with at least afternoon shade. It grows 10-20 feet tall. The tree blooms in early spring before the foliage emerges and is covered in lacy white flowers. This tree is native to the eastern U.S. including northern Florida. Prunus umbellata, the Flatwoods Plum, is a Florida native growing 10-15 feet tall. It is deciduous and is covered with small white flowers in early spring. It is an understory tree and grows best in a shaded location. It bears small purple plums in summer. The fruits are bitter but are loved by birds. A similar Florida native, P. angustifolia, is the Chickasaw Plum. It is similar to P. umbellata but this one suckers heavily and forms small colonies.

Flowering trees are an importantcomponent of central Florida landscapes.They provide colorful flowers during theirseason of bloom. Many of these trees alsomake nice shade specimens.
