About Autumn Olive: An Invasive Species in Maryland

Life cycle/information: This deciduous woody plant was introduced from Asia to the United States in 1830. Autumn olive was used for ornamental gardens, windbreaks, wildlife cover, and restoration of soils degraded by deforestation and mining. It displaces native plants by creating dense shade, altering soil chemistry, and interfering with natural plant succession. The related Russian olive (Elaeagnus angustifolia) is also invasive in Maryland.

Growth habit: Fast growing and invasive. This deciduous, multi-stemmed shrub or single trunked tree can grow to 20’ or more in height. Leaves are alternate along the stems, ovate to lanceolate, with smooth margins. Silver scales are apparent on leaves, buds, and stems. Undersides of the leaves have a silvery sheen. Small, creamy yellow, aromatic flowers bloom in the spring. Produces small round reddish fruits dotted with scales.

Reproduction: Produces a large amount of seeds with a high germination rate. Seeds are dispersed by birds and mammals. Regrows easily when cut.

Conditions that favor growth:  Sun and partial shade. Prefers well-drained soils. Drought tolerant. Tolerates salt and soil pH as low as 4.0. Most often found in open forests, fields, and along streams and floodplains.

What to plant instead:  Winterberry (Ilex verticillata), spicebush (Lindera benzoin), gray dogwood (Cornus racemosa), Southern wax myrtle (Morella cerifera).
