[AG409] Biology and Management of Whitehead Broom in Pastures

Abstract

Whitehead broom (Spermacoce verticillata; Figure 1), also known as shrubby false buttonweed or southern larraflower, is becoming problematic in south Florida pastures, hayfields, and rights-of-way. With the first recorded herbarium specimen dates back to 1956, this plant was likely introduced into Florida during the late 1940s or early 1950s. Since this time, it has increased in cover throughout central and south Florida and has become a serious problem in pastures and hayfields. To date, there are few options for control of this species.
