Iva hayesiana


Hayes Iva, also known as San Diego marsh elder, is an evergreen shrub with a naturally sprawling habit with branches extending to 2 – 3 ft. tall and plants reaching 4 – 5 ft. wide. It is characterized by pale green leaves and spikes covered with tiny yellow flowers during spring.

Hayes Iva is a tough plant that is highly suited to sunny exposures and summer moist or dry conditions. It grows well in both clay and loam type soils throughout the Inland Empire. Throughout this range, Hayes Iva is most often grown on banks and slopes, in parkways and adjacent to natural areas as a low maintenance ground cover. It can be easily trimmed along walkways and topped to achieve a neat appearance.
