Zinnias are colorful, low-maintenance annuals that prefer warm weather and bright sunlight. Although zinnias are relatively disease-resistant, they are sometimes plagued by diseases that cause brown spots. The brown spots are usually caused by one of three types of leaf spot -- Alternaria leaf spot, bacterial leaf spot and Cercospora leaf spot.
Other less common conditions that can cause dark brown to black spots include: 1  Riehl melanosis: brown pigment condition on the neck and face. 2  Poikiloderma of Civattea: dry and scaly patches on the neck and face. 3  Erythromelanosisfollicularis. 4  Lineafusca: long skin markings.
