Vinca Diseases

With its tolerance for heat, drought and poor soil, annual vinca (Catharanthus roseus), also known as Madagascar periwinkle, is a very popular annual in South Carolina. It is commonly used for summer color in landscapes because of its durable, abundant flowers that last from June to frost and are available in a variety of colors. In addition, annual vinca is one of the most trouble-free bedding plants. It has no significant insect pests. However, disease problems such as root rots, stem rots and foliar diebacks can occur periodically. To learn more about these problems, see HGIC 2108, Vinca Diseases.
