Originating from tropical Latin America, it is a tender perennial that has adopted the habit of an annual when cultivated in temperate zones. A modest grower, it reaches a height and width of 1 to 3 feet. The plant presents a bounty of distinct, 2-inch blossoms primarily of a rich blue hue, though purple and white variants exist, all adorned with dark eyes smudged white. ​Widespread in the tropical Americas below 8,000 feet. Photographed in the department of Quindio, Colombia.
