As part of the University of Connecticut Cooperative Extension System Master Gardener Program, interns must complete the Tree, Vine and Shrub Identification Project. The project entails the creation of an ID notebook consisting of trees, vines and shrubs that are common to Connecticut. The purpose of the project is to learn about different plant characteristics, structures, growing conditions, and problems of the most commonly grown garden ornamental plants, as well as the principle invasive plants which pose a major problem in our state.
