Harrisia fragrans

fragrant prickly-apple cactus

Cacti are known for their large, showy flowers and this plant is no exception - the fragrant tubular flowers bloom at night and can be up to seven and a half inches long. The fruit is also edible. This is a rare Florida Keys species because much of its habitat has been destroyed for development. If you get your hands on a specimen for the landscape, it prefers part shade, as it is an understory plant in its habitat.
