Chocolate tree in bloom
Chocolate tree, Theobroma cacao.
Family: Malvaceae (Sterculiaceae alternatively ). In 2016, the label on this plant gives Malvaceae as the family, which is consistent with Wikipedia's current attribution.
Native to: deep tropical regions of the Americas
The blooms form all up and down the trunk, which is a rather unusual behavior, at least among plants I'm familiar with.
