About
Harrisia fragrans is a rare species of cactus known by the common name fragrant prickly apple. It is endemic to Florida, where it is known only from St. Lucie County. The plant's habitat has been almost completely consumed by development, leading to its rarity. It is a federally listed endangered species of the United States.
Where it grows
The plant's favored natural habitat is mostly coastal hammocks with some shade, as the cactus can become desiccated in full sun at elevations of 0-10 meters.
