One of the tropical plants growing in the butterfly room at the Calgary Zoo.

"Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colors exist as new varieties are being selected. The flowers typically change color as they mature, resulting in inflorescences that are two- or three-colored. A common name for Lantana camara is "Ham 'n Eggs" due to the adjacent pink and yellow inflorescences.' Maybe that is what the Lantana in my photos is?
