I have 3 sets each with 3 clusters of areca palms. They had grown wild (very dense) but I recently trimmed them so that the trunks are exposed and it's possible to see through them. However, the center of each of the clusters (where the trunks of each palm meet) looks messy and unattractive. I want to know whether there's a flower or plant that can be used to cover up the center of the areca cluster. Ideally, it'd be something colorful, that would thrive in the South Florida climate and would be able to grown on top of the arecas' trunks.

Thank you for any suggestions.
