Galinsoga (Galinsoga quadriradiata) is an erect (upright), herbaceous, short-lived warm-season annual weed in Florida landscapes, container nurseries, and other agricultural production systems. In nurseries and landscapes, galinsoga can be a troublesome weed, but it has been utilized by some cultures for food or medicinal purposes. This new 5-page article is written for green-industry professionals and others to aid in the identification and management of galinsoga in and around ornamental plants.
