Tropical plantings are the dominant factor that give this patio its tropical atmosphere. The rest of the courtyard design is fairly neutral and universal. The outdoor furniture and fountain are quite common and could be used in most any style of patio design, courtyard, garden, or landscaping.
As I mention repeatedly on this site, any single element can create atmosphere and influence the style of the garden or landscaping. And most often, the biggest influence is the type of plants you use. In this case, ti's tropical plants. In many design plans like this with a fountain that are otherwise neutral, it's possible to rotate design styles simply by periodically changing plant types.
