Hypericum cumulicola is a rare species of flowering plant in the family Hypericaceae known by the common name highlands scrub hypericum, or highlands scrub St. John’s wort. It is endemic to Florida, where it is threatened by habitat loss and degradation.  It is a federally listed endangered species of the United States.

This is a perennial herb with wiry, sometimes woody, stems growing from a taproot and reaching about 60 centimeters in maximum length. The leaves have slightly succulent blades which are linear in shape and measure just a few millimeters long. Flowers occur on the upper branches in a scattered fashion. Each has five yellow petals 3 to 4 millimeters long and many stamens at the center.  The flowers open in the morning and are closed by midday. They are visited most often by bees of genus Dialictus.
