Summary

Smilax maritima, commonly known as Lanceleaf Greenbrier, is an evergreen perennial vine native to coastal dunes, maritime forests, and wetlands in the Southeastern USA. It typically grows to a height and width of 3-5 feet (0.9-1.5 meters), with a sprawling habit that can form dense thickets. The plant features lance-shaped leaves and small, inconspicuous greenish-white flowers that bloom in the spring. It produces bluish-black berries that are attractive to wildlife. Lanceleaf Greenbrier is valued for its ability to stabilize soil in coastal areas and its use as a natural barrier due to its thorny stems.

Lanceleaf Greenbrier is adaptable to a range of light conditions, from full sun to part shade, and prefers moist to wet soils with good drainage. It is often used for erosion control, as ground cover in restoration projects, and as a wildlife-friendly planting. While it requires minimal maintenance once established, gardeners should be aware of its thorny stems when handling the plant. It can become aggressive in favorable conditions, so it may need to be managed to prevent it from overtaking other plantings.CC BY-SA 4.0
