Tropical Gardener answer: You’ll want to select trees that grow quickly to 12 to 20 feet and are heat and salt tolerant. Though you could probably choose from a list of a dozen trees, some may be easier to find at local nurseries than others. Eight that should be locally available and could work well in your location are described below.
Tahitian gardenia or tiare (Gardenia taitensis) has large white fragrant flowers and large dark green leaves. It grows moderately quickly with a shrub like growth habit that can be easily shaped to a single trunk tree. Mock orange (Murraya paniculata) grows quickly but needs protection from direct salt spray. It has small fragrant white flowers and dark green foliage. It can also be grown as a shrub or pruned into a small tree.
The crepe myrtle tree (Lagerstroemia indica) puts out seasonal masses of flowers that range from white to pink and purple. This tree does best in a rich soil and has a moderate growth rate. The flower masses are pretty but are not fragrant. The mgambo tree (Majidea zanguebarica) is a very interesting specimen plant sometimes known as Hawaiian pussy willow, Zanzibar soapberry or velvet seed. Its small green flowers develop into seed pods that burst open to reveal a bright red interior that houses several gray velvety seeds. The plant is quite showy when pods are present and the seeds are used culturally to make lovely lei.
The curry leaf tree (Murraya koenigii) has small edible green leaves that are used to lend a curry flavor to stews. The fragrant white flowers appear seasonally and are followed by deep purple berries. Plumerias offer wonderfully fragrant flowers. To be sure they can offer year round shade get Plumeria obtusa which has white flowers and leaves with a rounded tip. Several other varieties lose their leaves in winter, so be sure to get the obtusa. The native hibiscus arnattianus known as kokio keo keo is a hearty specimen plant that can be grown as a shrub or shaped into a tree. It has large fragrant white flowers with showy magenta stamens. It grows fairly quickly and flowers year round.
Sunrise Nursery has or can get most of these trees. Tropical Edibles Nursery carries edible and culturally useful plants. Other nurseries or plant departments at big box stores may carry some of these plants. Call around to find them.
